While
@Simon_Jester's post about the "trigger-happy admiral" is an important point, I think it's also important to clarify that you are... well, wrong, here.
The definition of Abhuman in 40k is "a stable, reproducing variant". Ogryns count because when two Ogryns have a kid, the kid is also an Ogryn. Notably, this means that the first example of a given abhuman breed isn't actually an abhuman - they're a mutant, and its only later when they survive to have kids that there is any evidence to support changing the classification to abhuman.
Mutants, then, are any deviation from the accepted norm that
isn't self-reproducing...
Hm. that's actually quite interesting. I hadn't heard that definition being formalized. You're sure?
Thats fair, and true but the reason I brought it up was because I got the impression that people were saying that being killed was the only response and I wanted to bring that no, it's not, its unfortunately common to be sure but its not the only way.
Does it
matter whether "the only response" the Imperium has to weird-looking people is to murder them, or whether it sometimes grudgingly tolerates the continued existence of a group of weird-looking people until or unless some Imperium official gets a bug up his ass and decides to murder them anyway?
Like, does this make the Imperium better in a
significant way, or are you just trying to score rhetorical points in the Imperium's favor on general principles?
This is also true, there is no good Chaos detector, but it ignores that they do try...
Because
it doesn't matter that they "try" if their methods of "trying" are fundamentally bullshit. If they lack the tools to figure out whether a local colony has webbed feet because of mutagenic chemicals in the water or because of Tzeentch, then they're basically just blowing up weird-looking people at random.
It doesn't matter that they
say they are doing a scientific study of which weird-looking people are Chaos mutants to be murdered and which are sometimes-tolerable abhumans. For all we know, they're basically just doing phrenology or some bullshit like that, something with no scientific basis whatsoever and that is far more likely to kill random innocents while letting actual servants of the Ruinous Powers slip through the security system.
It doesn't matter that the Imperium is "trying" if they cannot succeed,
know they cannot succeed, and commit the same atrocities anyway while patting themselves on the back for how good and righteous they are for "trying" in a way that always only ever reinforces their own biases.
I've heard of it yeah, haven't had it really explained to me though so I assume it's don't ask, and if someone does ask, don't tell
See
@Tithed_Verse 's point.
To summarize, there is a
longstanding and strong pattern of LBGTQ people being oppressed, and in the modern day this oppression tends to involve people who say "I'm not homophobic
but I don't want to see too much overt gayness in public." The same thing happens to other minorities: "I'm not racist
but gee there sure are a lot of people around who speak Spanish, it bothers me." Or "I'm not sexist
but I feel henpecked taking orders from all these female supervisors."
Having lost the public argument for "society should be allowed to discriminate against groups it does not like," the nasty types have fallen back on "okay, we'll officially tolerate these groups but quietly crush them if they are 'too much' or 'too obvious,' and expect them to keep on hiding and walking small so we can
pretend they don't exist and so they know they're still in a subordinate place."
"You have a right to exist as long as we don't feel ilke you're existing
too hard and too much" isn't good enough to be satisfactory for LBGTQ rights or representation anymore. Because straight/cis people don't have to walk small and pretend not to be "blatant," so why should queer/trans people?
...
So there's a long history of LBGTQ people being told "you can do what you like but don't be too blatant about it" as a means of continuing the oppression after it stops being legal to just randomly murder LBGTQ people spontaneously.
As a result, no LBGTQ person is likely to take you seriously when you say "the Imperium's perspective on sexuality is that it's allowed
as long as you're not too blatant about it." It's like telling a black person that segregation is fine as long as the facilities are "separate but equal."
Everyone already knows it's a fiction, and knows what the fiction means.
And frankly, in this case i think you're just repeating the fiction uncritically, and without realizing that it is a fiction, because you're too accustomed to taking these things at face value. Even if you, personally, are not homophobic, it doesn't mean you can't be taken in by a disguised homophobic argument that LGBTQ people will recognize for what it is
and that you do not.
Well that's fucked up
Yeah, I know, right?
So I hope you understand why LBGTQ people, and people who are not themselves LBGTQ but know the history, aren't very sympathetic to something like:
"The Empire isn't anti-gay, it's just opposed to gays being
too obvious and visible about that."
