New to the show

Excuse my tag but I am new to the housewives show and on season 1. What is with these girls and mentioning about being black all the time and shaming the biracial women. Also I never hear the white girls in the other shows going on about being white. Am I missing something wtf 😬 also Iam from South Africa 🇿🇦 and Robyn & Gizelle went on about Micheal spanking the other guys butt , they would shit themselves the African men in South Africa often walk around holding hands and no one cares. I mean these woman need to get out more lol 😂
