Generally agree with all of this.
I will say I find the second much more sympathetic than most seem to. I think he's straight up right about the incest, and it's very weird how much of the fandom excuses or pretends that's normal, and that's something I'd honestly like Rhaenyra to get away from and drop entirely.
Uh, remember, he's not just saying the incest is bad, he's saying "because of the incest, the Targaryens are polluted human beings who shouldn't set foot in the north."
Like, it's in no way
Viserys' fault that his parents were brother and sister, and it's not Rhaenyra's fault her parents were first cousins. If we
don't treat the argument "the Targaryens are children of incest and therefore have no right to rule or even to set foot in the Seven Kingdoms" as treason, then that doesn't just affect Viserys I. It affects everyone in the royal family, including Rhaenyra herself and including her future children even if Rhaenyra's children are fathered by someone comfortably out of the family tree.
Basically, the price of "being a Targaryen and wanting to rule Westeros some day" is that you absolutely cannot tolerate any suggestion that your ancestors' incest invalidates who you are as a person or invalidates your right to rule. If you accept the premise that Rhaenyra actually should be queen some day, then that's pretty literally treasonous talk right there.

Rhaenyra's future right to rule)
Yes it was remarkably stupid of him to say, but he was drunk, and yes it is stupid to get drunk if you're the kind of person who says true things that will probably get you executed when drunk, but stupidity does not warrant death.
The problem is that if you start letting relatively unimportant people get away with saying it because they were drunk, soon you have to deal with important people saying it "because they were drunk and just being honest," and within a generation or two (that is, within the timescale of Rhaenyra's reign) it starts getting out of control.
It's not great, but we're RPing as a feudal monarch or someone who intends to live long enough to become one, y'know?
