That doesn't really make sense. It's a very dismissive thing to say. you probably use "they" a few times a day at least.

Do you know about sexual dimorphism in humans? Do you know that gender isn't biological? Do you know that preferred pronouns can also be isolated from the idea of gender? Yea idk. Open your mind and do some research

Yep and nobody is disagreeing with you there

I personally prefer they/them or he/they so it's not like I'm completely confused by choosing your own pronouns,,,,,, but xe/ze does just feel kinda pointless to me. "They/them" is perfectly fine and doesn't make you sound like an alien, but idk maybe I'm missing something

That's because the movies in the "he" section were basically all made with 8 year old boys in mind. Take it as a good thing that your taste doesn't completely align with that lol

Princess Mononoke is so good that everyone likes it.

Also, Why the Xer pronouns and not just they/them? I don't know anybody that goes by Xer, but I know many people who prefer "they". Just curious.
