If you mention that to them when it comes to Wonder Woman and other female characters, they scream that it doesn't matter and it's still offensive. Yet, they will use the same excuse they condemn other people for using to defend Sailor Moon and the scouts.
IMO the majority of these people are the female equivalent of a basement dweller; terrified of the opposite sex for no reason, live in a delusional fantasy land where someone else has to fix the problems, a strong fixation with childish fantasies/media, unhealthy attachment to their sexual fantasies, complete disconnect from how the real world works, obsessive need to belong to a group... the list goes on and on. It's just that now, with the internet, they can contact each other without having to leave their houses.
They probably have a normal/slightly high level of anxiety that has been allowed to fester into this unholy mess.
You know would call out from work to take their badly done and ironic signs to protest the inauguration of a democratically elected president like they've been doing for the past few weeks because they're upset the other lizard didn't win?
