Gay men are oppressed for being FEMININE.
Hence they perform FEMININITY.
Performing masculinity would, by definition, be conforming to societal expectations.
What part of this are you not getting?
Ooh, I don't know. maybe the part about where FEMININITY involves males dressing up in highly sexualised clothing, stopping their shows to deliver babies and to throw into the audience with the exclamation of 'another black one'? Is that feminine?
Maybe it is the part where FEMININITY, involves taking a small girl that was murdered, and more than likely abused, certainly objectified, and using it as a name for people's entertainment? Is that feminine?
Maybe it is calling each other bitches and exaggerated mannerisms? Is that feminine is, or is that a MALE's view of what FEMININITY is?
What part of this are you not getting?
Probably the part where any drag queen parodying what they perceive as being a woman as FEMININITY?
Or maybe we are not getting how you, yourself, have a such a very misogynistic view on what FEMININITY is?
