It's also not as black and white in the US despite the popular narrative. Blackface was an avenue of opportunity for freed black slaves to gain social visibility while at the same time a way for white people to slowly introduce black culture into the narrative. The practice of comedy at the expense of black slave stereotypes has fallen out of practice because it's no longer culturally relevant, for sure, but "coon" culture had an important role to play in US history. A modern analog might be hip hop. Eminem and other white rappers arguably don black-speak to participate in a scene that idolizes, or celebrates, the struggles of low income, predominately black, communities. But the art tells an important story. And it's great music!

same with nudity, and this puritan obsession pushed by US megacorps...
