This sort of things, for example. I am more familiar with the UK, France, and Germany, but your example is on point.

I suspect at the beginning there is a kind of identification and a contrarian reflex (“you won’t prevent me from speaking so I will say the vilest things just to test how far you’ll bend”). But people doing that end up taking it seriously after having steeped in it for a couple of years. Still, surely they realise that the people they support don’t care a bit about them and live on the other side of the world.
