That's my take, yeah. It's one thing to talk about how unfair it is that trans people have to be mindful of this. It's a whole 'nother thing when you're actively encouraging it by criticizing a victim. Like I said, we do not see this kind of victim blaming - at least not permissibly - for other protected classes. A woman is raped, anyone who blames her for her outfit or for being in a bad part of town gets a grey name. A black person is unjustly killed by police while running, the only people who criticize the person for running has a grey name. All I want to see is some consistency, you know? Not to say that mods are turning a blind eye, but I'm seeing some posts where, if certain details were flipped, I don't think would be as permissible as they are.
tl;dr Finger waving at a victim of a horrible hate crime is pretty darn victim blamey.
