Voluntary diversity has helped. Not desegregation. Desegregation is a forced diversity and is malicious at best. Thus, the rest of your posting is necessarily built on a false premise.
Politics aside, all three of those names have higher character qualities than Bill Clinton or Donald Trump.
There is no such thing as equality of opportunity and your posting does not address my posting whatsoballsout. It's quite evident that you are on your 7th Cosmopolitan.
White people are also responsible for a good deal of destruction on the planet as well. Hitler and his henchmen were white. The Catholic leaders who brought on so much destruction in history were white. The South African aparthied guys were white. All this proves is more white people were in a position of influence on the planet then other groups. You get good and bad out of people regardless of their race or skin colour. Put them in power or back them with resources like money and things happen. In recent times, Asian people have contributed hugely to society. Blended families are everywhere and some really wonderful kids are going to change the world. Your need to categorize is useless. It's also racist in nature. Not acceptable to most, and particularly not acceptable to me a white man with mixed children. Enough that you'd have a real problem if you uttered your "truth" in person around me.
"White people" have not been responsible for anything good or bad at any time in history. Stop the identity race baiting garbage.
