Rubbish!
This 'black' victimhood is bullshit. Different people's have different cultures and traditions. For many African and other non-European cultures, celebrating through song is kawaida. For Europeans not so much, but they tend to clap a lot.
Just go to any European street and perform something, even a shitty traditional dance, and see how many people are gonna stop and clap for you...
Having said that, South Africans and Kenyans need to decolonise themselves...
