Chillax, guys. It's like homosexuality all over again. And you don't see everyone up and just BECOMING GAY overnight just because it's hip and trendy now, do you?
It's like the progressive waves of Xsploitation trends over the last few decades. You had sex, black people, gay people, and probably a dozen others I can't remember but you get the point.
Don't worry, internet. Your vaguely-defined heterosexuality is safe.
