in don't wanna get too heavy with psycho analysis but its like this. The difference between a black men in NYC, Chicago, LA is gonna quite different from a cat in Alabama, Virginia or anywhere else down south for the most part. Similarly in South Africa black people in the big cities are pretty much 21st century hybrids, they are hip hop, pop culture, techno savy etc. The fact they are Zulu or Xhosa is not that significant per se. But if you go smaller areas and town then its a much larger factor.
No one comes to the US to visit Missouri or Arizona, let alone Alabama etc (sorry to all my mid west and down south Coli brehs
), similarly you wont really come to South Africa to visit small towns so all that tribal shyt will not affect you in anyway.
Especially in Cape Town....matter of fact some Swedish tourist CACs might start taking pictures of you
It's not everyday that they see clothed, seemingly civilized monkeys
