It is strange that many people on this forum advocate racism towards other races
You sir, have a very selective reading comprehension if that what you found on this forum. Either you're leftie (not liberal but leftie) or you're dumb as an ashtray. Nobody is advocating racism on this forum but as in very community some people express racist views and sometimes they're racists.
You seem to want the freedom to racially abuse ethnic minorities and are then surprised when people are then intolerant towards you.
You seem to be unable to differentiate between theoretical debate on a internet forum as to what kind of immigrants to Poland people would rather have and reality on the ground for those who happened to be immigrants themselves..
If you imply that there is some kind of connection between being racists and being on the receiving end of a racist prejudice - you're an idiot.
On the top if it you're confused as to proper terms for those attitudes.
Racist doesn't take kindly to folk with a different skin tone than his own. A xenophobe hate all foreigners regardless of their race.
Between feelings and an action there is a threshold, not all racist or xenophobes are able or willing to risk it. Only mindless scum from the gutters and there is no excuse for them. Althought you seem to be more than happy to provide that excuse for them.
As they say - each for each own.
that African-Americans benefited from slavery
Well, their ancestors who have been slaves - no. Indirectly their progeny benefited from slavery. That one is obvious.
