Sorry reverse racism whatever the skin color does exist. Anyone can be racist. Go read a history book. White slavery and oppression has happen in ancient times, might not be a lot now, but it was throughout history. Ottoman Empire, Ancient Rome, Slavic slaves etc.. So, yes white people have experienced oppression, as have all other races.

Modern oppression of blacks has been horrific but other races have experienced it too. If you're going to be racist for racist things that happened in the past, chances are you're racist. Best thing would be for no one to be racist or if will never end.
