Man I hate when people are like that, gay flatmate I had would say "You guys are so clean for straight men" and Im just like, wth man, thats prejudice. Imagine if I went around saying "You are so clean for gay men!"
Except only one way it "swings" has any power behind it and actually causes real life oppression, so no, it doesn't swing both ways, and being the butt of a generalisation doesn't make you equal or even comparable to people who are actually marginalised.
So sick of this "reverse bigotry" bullshit, it's nothing but privileged people desperately craving some victimhood. It's gross.
