Hah. I guess I lost you because I never quite made the jump into buying the notion of considering the way they look or act as an identitarian problem. This is a trend across the political divide, from fashy complaints about people with "blue hair" to progressives challenging gender stereotypes. Seems to me like a problem of aesthetics, all of it, but people have associated those aesthetics to political positions, when not with their mutual perception of their fundamental identities.

Which of those forms of expression floats your boat... you know, biologically, is entirely up to you and your natural reactions. Dress, hair, lack of hair, sexual practices, participation of specific varieties of genitalia... I don't care, it's all some interaction of how you decorate yourself and which decorations get you going.

But I'm in the minority there. It's clearly important to society and it can have a deep impact on individuals and their wellbeing. And like anything relevant to society it's been politicized. Because we're all just horny apes in the end.
