It's not really necessary, If anyone ever misgenders you, You can just say "Actually i'm a *blank*"
Not just that, Haters use those kinds of bio to piss people off even more
I NOTICED THAT A LOT OF YOU DON’T HAVE YOUR PRONOUNS IN YOUR BIO. IT’S REALLY EASY TO DO, AND IT JUST MAKES IT THAT MUCH EASIER FOR MEMBERS OF THE TRANS COMMUNITY, WHETHER YOU ARE CIS OR NOT. SO PLEASE, ADD YOUR PRONOUNS TO YOUR BIO.
