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.
The traditional answer is that yes that is what sex is, but gender is a social role that isn’t “what sex you wish you were” but relates to the various performed aspects of being male or female (etc.) Being really strict, there is “gender identity”, the gender you self-identify with, and “gender,” what society perceives you as (equivalent to if you pass or not).
