I love how in the entire history of the feminist movement we have ONE act of violence by Valerie Solanas, and it's always brought up as an example of how evil feminists are. Despite the fact that...er...Solanas was deemed unfit to stand trial and insane by reason of having schizophrenia and she wasn't at all coherent about her motivations for shooting Warhol. It's not exactly like Elliot Roger or the Ecole Polytechnique massacre, is it?
Also the reason we bring up trans murderers or attempted murderers is because their motives are important, not their trans status. Myra Hindley was a woman, but she didn't kill children because she was a woman or because she was a feminist (I don't even think she was a feminist.) But take, for example, the attempted axe murderer Evie Amati. Evie admitted to trying to murder three strangers because they had earlier been rejected on a dating app by a woman. Evie then spiralled into a fit of rage because they perceived they had been rejected for being trans.
