Meh. I agree but it is what it is.
History happens. Can't get too upset about racism. Racism is a new concept generally. Tribalism is all racism really is and tribalism is a far more tenured ideology than liberalism. I don't blame anybody for being tribal and that means racist. It is what it is.
If Euros had been slaved to Africa by African kings I wouldn't blame those Euros descendents for being racist and or tribalist. How could you really? It's to be expected in such a situation. I don't think you can really blame people though on any side. It was always going to be that way with what happened.
