Everything you listed is from the past though. I'm white. Am I to be held accountable for the slave trade in America, the holocaust in Nazi Germany and racial segregation of the 1900s just because of my skin colour?

No. They were tragedies. But I had nothing to do with them. So to say "white people are the most racist race because of all these historical tragedies from the past few centuries" is racist. I'm not racist. Why should I be generalised as being racist because of all those horrible events in the past that I had nothing to do with?

Don't act like you don't know I'm referring to the modern slave trade of black people from Africa. Never before in history has slavery existed targeting ONE specific race in that way, with their race being the sole reason for them being slaves in the countries where it's practiced.

White people didn't create the concept of race or the slave trade, sweetie. As much as you'd love to 'blame it on the white demons!' you should know that people have been oppressing people who look different than them since the very beginning, white or not.

ATRL really isn't the venue for this discussion huh?

The concept of race as we understand it today did not exist before colonialism, sweetie. "White people" was not a thing until then, look it up, sweetie.
