I don't argue against the idea Vriska is hated because of misogyny as well, but I do think it's a bit of a tired critique to wash her hands of any kind of sin because IRL people are bigoted.
Vriska literally paralyzed Tavros; and he doesn't really ever get a moment of catharsis, he exists only to serve her arc which is DEFINITELY a critique that can be had about her story.

Dirk was also an abused character, I don't think it's fair to just wash that away either and say that because his glasses became part of the soul juju that he is emblematic of patriarchal violence through and through. Otherwise, what's the point of his discussion with Dave at the end of Homestuck? Lol.
