I have noticed the same thing my self and that is racisim by blacks towards whites, I have never in my lifetime owned a slave or anyone who has. What happend to your greatgreatgrandfather has noting to do with me. I for one think that we all should be gratefull for the things that have been given to the world by blacks. Where I live there is a war going on between blacks and other blacks shooting and killing each other. Still we have many robberies and shooting of inocent people of all races.
