I once ran up against a guy who claimed trans people had their minds rotten by the porn industry. Motherfucker, there are really well documented non-cishet-normative social classes in Norse Scandinavia, in pre-Modern Albania, in pre-Muslim Arabia, in several places of Indonesia - what porn industry did exist there!? He couldn’t come up with anything, but wouldn’t budge either. Some people get stuck in a prejudice and will behave like raving conspiracy theorists the moment they’re offered some bullshit explanation that makes no sense but agrees with them.
