MELTING POT AND NEO-RACISM

America was designed to be a melting pot for humanity. We are all be in the same game together with equal rights. The politically correct term “diversity” is just a euphemism for reinstating segregation.  By definition the goal of diversity is to separate us based on race or other cultural/religious criteria. That was the concept that so many sacrificed, even with their lives, to eliminate in the 60’s. Why are those self-proclaimed “liberals” that benefited from those sacrifices in blood and tears promoting neo-racism?
