Honestly the idea that the sexual abuse that Tyrion suffered was “not as bad” or not as important as what happened to Tysha is a logical fallacy that promotes victim blaming. There is no heirarchy of abuse, there is no one whose suffering is worse or the most important to talk about. This is the literal reason why many victims think that their abuse was not valid or severe enough to talk about. This is a problem not only in the fandom but in the text itself, because I’m not even sure that GRRM knows he wrote Tyrion as a rape victim, but that is what he is.
And what makes this very meta is that Tyrion himself does not and would not consider himself a rape victim, which is why he spends so much time thinking about and trying to rationalize it as what he did to Tysha, instead of something his father did to him.
I get that people are upset that Tysha is a character who is important in the text only in how she appears in Tyrion’s story, and I am just as tired as you are of male stories being built on the backs of brutalized and voiceless women, but when you deny Tyrion the right to feel like a victim in a situation where he was forced into abusive sex as a thirteen year old, when you say that what he suffered “cannot compare” to Tysha’s suffering or is not as important, you are saying that some abuses are more important than others and some abuse victims are unimportant, you are denying victims everywhere their right to feel that their abuse was enough or opening the door for them to question whether it even happened. And disabled abuse victims like Tyrion are even more likely both to be abused and to internalize the message that they are not important enough. You are telling them not to talk about or report abuse, and that no one will listen if they did. None of it should have happened, to Tyrion or Tysha.
