But some White tourists posing naked a top a sand dune, is not?

But it's not just the sand dune, I've wondered in general why it's okay for indigenous tribes to walk around naked/topless in Africa wherever they please, but not for anyone else. Why is indigenous nudity treated different from modern people nudity?

In Latin America, tribes usually cover up when they need to go into the city for something.

Is this an example of black imperialism?
