In the abstract, yes, but when a group of people is oppressed because of one of those identifiers, it stops just being a born trait. It also identifies that you’re oppressed. Celebrating who you are with regards to that kind of trait (sexuality, sex, race, etc) isn’t a celebration of being born a certain way. It’s a celebration of self acceptance, and an act of rebellion.

You aren’t proud of what you were born with, you’re proud of what you were born with, because some people have tried to punish you for that what.
