Actually, it’s refreshing to know the truth. There was never anything wrong with “white” people. They should let go of the enforced guilt.
All people are naturally “racist” to some extent. There is nothing wrong with a preference for the appearance and behaviors of others. In fact, there are good biological and sociological motivations driving this to be a dominant characteristic.
Slavery has existed for as long as Man. Only those who are actual slaves are the victims. America had Africans and Chinese and probably others as slaves. Some have let the past be in the past, some have not.
If you want to blame someone for black slavery in America, blame the British. They’re the ones who made it into a business, since shipping was about all they had to offer.
Chinese slaves? Really?
There is slavery today in the muslim world and sweatshops in China with little public outcry or concern.
