Blacks never did have that protection.
You don't get to be part of a race that oppressed black people overtly for 349 years and covertly for 52 without being held to account. That's what you're calling black racism. And that's like calling a person who killed an armed person who was trying to invade that persons home a murderer.
Really? The whole race did it? Every white person in the entire planet oppressed black people for 349 years? When I was beaten by black people for much of my childhood, can we say that every black person beat me for 9 years?
You really are a racist. I can understand why a black person might struggle with racism but that doesn't make it acceptable. I was abused by black and hispanic people through most of my childhood and I could be racist but I choose not to be. Since you weren't alive for the 349 years of overt racism, and you don't remember it, and you didn't experience it, it is not justification for you to be a racist. Tell us about what the white race did to you personally.
