It doesn’t affect me. That being said “policing” is a hyperbole. Obviously no one is forcing people to swear, they are just giving them shit when they censor themselves. Those people can still choose to censor themselves even when someone tells them it’s ok to swear.
It’s no more policing than OP ‘policing’ people to not ‘police’ him.
People have opinions. You can’t request others to not have their opinions if you’re going to share yours.
