Who said anything about a single ship being the military backup? In a situation like what has been proposed Team RWBY are a scout unit. If they find something they need to be able to radio it in (thus the relay scout ship which, to be fair, could have easily been the Bullhead that dropped them off.) From there reinforcements would be called in. Meaning Ironwood's fleet over Vale plus any Hunters that the Valesian government decided to send.
... Isn't that exactly what happened anyway? Ironwood wanted to send in the troops immediately and Ozpin said they should scout it out first. For all we know, Oobleck was carrying a radio in that huge pack on his back. It wouldn't have been useful anyway, since they were several meters underground by the time he actually figured out where the White Fang was and what they were doing.
Torture doesn't speak well of someone mental faculties.
And construing anything I've ever seen Yang do as "torture" doesn't speak well of my ability to take someone seriously on this subject. Speaking of which:
1. In our introduction to Yang, we see her sexually assault and then beat up a bunch of criminals for no reason, even after they proved willing to de-escalate. She may have even killed a few of the mooks, its hard to say (and more to the point, there's no way if SHE could have known if she was killing any, given the way aura supposedly works...most of the time at least, aura is not very consistent).
She needed information and presumably a student Huntress whose dad is a teacher doesn't make the money to pay a shady information broker's rates, so she did what just about every action hero and vigilante in fiction from McClane to Bauer to
Batman does and roughed up some crooks to get the answers she wanted. To claim they were willing to "deescalate" rings hollow to me, as Junior promised retribution the moment Yang let go of his balls and his goons were circling her with weapons drawn. I suppose you can take his bemused acceptance of Yang's offer to "kiss and make up" that way, but I personally doubt he would have actually let it end there and just went along with it to score a kiss before he made her pay.
2. We then see her abandon Ruby to disappear into a crowd of "friends" who we never see her interact with again, and indeed we never even see any further implications that Yang HAS any friends outside of the named cast. This is followed immediately by Yang SEPARATING Ruby from the one friend she's made since then (Jaune) at the assembly, and then - an episode or two later - telling Ruby that she should make her own team with new friends of her own before doing a 180 and going looking for Ruby herself as soon as they were actually in the forest. It definitely seems like there's a pattern of Yang trying to socially isolate Ruby while trying to convince her that she, herself, is much more socially apt than she is.
a. Yang ditches Ruby because she wants Ruby to make friends and not just hide in her shadow the whole time they're at Beacon (because what
teenage older sibling seriously wants their younger sibling hanging around them
all the time at school?). Ruby had specifically expressed that she was okay with not having any friends at Beacon since she had Yang, so Yang essentially tried to push Ruby into the pool to get her to swim (and she
does know how to swim, metaphorically speaking, since she had friends at Signal).
b. Okay, so those faceless shadow people don't show up again. Huge shock. What's your point? No one
else in the main cast was ever shown hanging out with background characters, and I doubt they were all friendless recluses or "psychopaths," so I fail to see why this matters.
c. Yang does not "separate" Ruby from Jaune, she waves at her sister and says that she "saved [her] a spot." Ruby runs off and leaves Jaune behind on her own.
d. In the locker room, Ruby starts acting happy about the fact that she doesn't have to bother with "awkward getting-to-know-you stuff" anymore and can just shoot things with Crescent Rose. Yang then replies that she's going to be on a team and needs to learn to meet knew people and work together with them. Ruby tries to deny this until Yang brings up teams, Ruby says that she'll just be on Yang's team, and Yang reacts by suggesting that Ruby try to form her own team (as opposed to, again, just lingering in her sister's shadow). Ruby takes this poorly, thinking Yang doesn't want to be on a team with her, and Yang quickly denies that and explains that she just thinks it'll help Ruby break out of her shell, which Ruby again takes poorly.
e. Once in the forest, Yang isn't specifically seeking Ruby out the way Ruby is seeking Yang; she asks if "anyone" is out there, then hears a whoosh of something moving quickly (Blake) and then a rustle in the bushes (an Ursa) and thinks it's Ruby. Yang isn't
opposed to being on Ruby's team - she only hesitantly suggests that Ruby think about forming her own team - but as the above shows, she thinks it'd be good for Ruby to make her own friends and team at Beacon instead of trailing along after Yang. The worst you could say is that she's too pushy in trying to get Ruby to open up and be more social and that it's probably not the best strategy. But to claim manipulation or psychopathy out of that...? I feel like you're throwing around a
very strong word whose meaning you don't seem to grasp.
2. We then see her abandon Ruby to disappear into a crowd of "friends" who we never see her interact with again, and indeed we never even see any further implications that Yang HAS any friends outside of the named cast. This is followed immediately by Yang SEPARATING Ruby from the one friend she's made since then (Jaune) at the assembly, and then - an episode or two later - telling Ruby that she should make her own team with new friends of her own before doing a 180 and going looking for Ruby herself as soon as they were actually in the forest. It definitely seems like there's a pattern of Yang trying to socially isolate Ruby while trying to convince her that she, herself, is much more socially apt than she is.
3. You mean the Ursa that destroyed her hair, something she is established to be very protective of, in the manage specifically cos Ruby likes it?
Probably referring to Yang's "I can't take it anymore! Can everyone just chill out for two seconds before something crazy happens again?!" thing when they're getting the chess pieces and people and Grimm keep showing up in weird ways. Which is painfully misconstrued either way, because it's so obviously just a silly gag that there's literally the sound of a timer counting off two seconds immediately afterward, and even if it wasn't to say that having a short temper and yelling out in frustration at weird stuff happening in quick succession and not allowing you to get a word in edgewise is a sign of
psychopathy is too ridiculous for me to even bother with.
4. In the following season, we see her encouraging Jaune to keep hitting on Weiss even though she knows Weiss is just irritated by him, and then uses the opportunity to call Weiss an "ice queen" when Jaune escalates.
I guess you could use this to argue that Yang is kind of a jerk, or that she has bad opinions/perspective regarding relationships, much like entire generations of women who grew up on awful Rom-Coms that glorified the exact behavior Jaune shows. I wasn't aware that that made one a
psychopath, though. Good to know!
5. Shortly later, she encourages her teammates to leave a dog - her OWN FAMILY PET - alone without food for a week.
There was a huge pile of food. They asked how Zwei would get to it, a can opener fell out, and Yang said that that settled it. In other words, Yang believes that Zwei can use that can opener to get to the food in some manner. Ruby did not protest this conclusion that Zwei would not starve to death in their absence, taking him along purely because he started giving her sad puppy eyes. And seeing as Zwei is
her dog, and not
yours, I think she has a better grasp of what he's capable of than you are. If Ruby did not express any kind of concern at his survival, we can probably accept that he would, in fact, be able to eat that dog food on his own.
So are you going to do this whole "What about x" whenever this comes up?
Just because other fictional characters commit some moral wrongs doesn't mean I can criticize Yang for the same things.
No, but it does mean that you're just refusing to accept a trope for what it is and instead choose to assume that it makes the character a psychopath/idiot/whatever. It's like bitching about how Superman is an evil bastard who wants people to suffer and be reliant on him because he isn't handing out Kryptonian tech and free energy: you're choosing to characterize Superman as pure evil instead of simply accepting that the writers want to write a superhero comic instead of sci-fi and either making peace with that or giving up on mainstream superhero comics.
