1. How did W.E.B. feel African Americans should<br> overcome discrimination?
zhuklara [117]

That communist boon's opinion should not be regarded. The best way would be a race war which would easily resolve the problem, second best is deportation to Africa where they belong. You can thank the jews for bringing them here and giving them an equal foot, today it is whites who are legally discriminated against anyways. Affirmative action, "anti-discrimination laws", EBT/Food Stamps, Welfare, Disability, Loans, organizations and institutional support, etc. They should be on their knees thanking us for our support and blessings, but that's not within their genetic nor spiritual character or nature.
