Keep posting - it's actually refreshing to see comments like yours, since they are removed from facebook or twitter for being "hate speech", while the radical left advocates for violence against groups they don't like by playing victim.
I can't agree with your statement, since in the US, blacks were brought as slaves against their will, but I find it still more truthful (migrant crisis and forced multiculturalism, as examples) than the radical left's insanity.
THE US ended the legal importation of slaves in like 1807. Most of them were brought here against their will when the colonies were under control of the Europeans. Don't try to lessen the European's culpability by blaming it on the damn Yankees. The Arabs and the Africans themselves had a role too.
