Unless you are legitimately an alien or a cat or something that somehow got on Lemmy (and I apologize if this is the case), then you are a human. You can’t identify your way out of being a member of this species.
The fact my fellow autistic people are disidentifying from humanity is extremely concerning. Even worse I can understand why given the behaviour of so many humans being what it is. Plus constantly being marginalized in human societies doesn’t help.
The solution though isn’t to stop identifying as being human and pretend to be something else. The solution is to re-evaluate what being human is. Too much emphasis in popular culture is placed on humanity or being human as some positive thing where someone who is truly human couldn’t be the villain or the mass murderer. The reality is the human race is broad and doing a genocide is just as human as inventing the vaccine for TB. Those things we can do because we are human, with human capabilities. Another animal wouldn’t think to make a vaccine, or to do a genocide, they do what they because of instincts, learned behavior, and survival.
