An identity almost definitionally can change because it's what someone identifies as. It's not necessarily transphobic to believe that, again it's all about letting people choose what makes them happiest!
It's also fine to think that being trans is more than an identity, but that's more of a theoretical or analytical (and complicated) discussion .
For political and simplistic purposes just allowing people to choose their identities has all the practical benefit we need.
Baby boop you've gotta let people choose their best paths. Just cause a guy wears pink or gets piercings or paints his nails or wears a skirt doesn't make him a trans girl. All of those thing or "normal" are just things you and other people choose to associate with being a woman. Let the people be free babes!
Almost certainly not real ๐
I wanna see the number on that little box climbing up on Lemmy as well!
I can't vibe being sleepy guy, but almost there.
It's all smiles and two little green stick arms!
Well I draw the line where they draw the line, if they say they're cis I believe them if they say they're trans I believe them. Easy as!
