People in the US will never ever accept racism, or the "soft bigotry" of the alt-right.
I have heard the scientific arguments about race, but that's the problem with generalizing, it's factually wrong.
THere are many people of color who achieve scientific greatness. There are many POC who are good decent, hardworking people, upstanding citizens.
THere are many POC who have died for our country. There are Muslims who have died for this country, even.
None of this justifies the "reverse racism" we see in crap like BLM or ever stuff like "BET" or "black history month" etc. etc.
