Heteronormativity
That is nothing new at all; both queer-theory and neo-conservatism differ from their common ideological ancestor only in the precise identity of the Born Evil and Oppressive crowd.

When you are just starting to fight for your rights, the lack of rights are so systematic and endemic it is very literally "all of society" that is against you. Eventually, that changes of course... but it takes a while.
Funny thing about that. When the feminists were just starting to fight, those were the first-wave feminists, who did not blame the Big Nasty Overclass for everything in quite that manner.
I'm sure most blacks saw all whitey as "the man". An attitude that, fortunately for all of us, Martin Luther King, Jr. saw his way around.
