If we are all suppose to be happy loving an excepting...?

why is it everyone thinks everyone is raciest. there is evidence of whites being in america before the indans they killed them off when we returned we killed some of them off when whites went to Africa the blacks already had black slaves from defeating other tribes and the whites needed workers and the blacks need supplies that we had and so on and so forth races have been fighting and trading people forever thing is if your going to live in this country WE ARE AMERICANS that's all there is to it if i have to describe someone to someone else im not raciest because i said he was black or brown or yellow the fact of the matter is racism starts and stops with us the past it the past so why do others still use the race card and white people are the problem ?
