semi- Serious question, Idon’t get it. Most of us get why the hegemonic gender system is stupid, why subscribe to the binary role you were assigned? Also, why do straight people exist? Maybe it’s just me but I like to look and feel like my own perception of what is attractive.
I don't think that anyone's preferences or identity is any less genuinely theirs just because they were influenced by culture. Moreover, what we find attractive can vary greatly from person to person, even within the binary norm.
