Blacks, even middle class blacks, score much worse on IQ tests and college entrance exams than whites and asians. Predominantly black high schools are an abomination. Without affirmative action preferences, most blacks could not gain entrance to even middling colleges. Since virtually all blacks cannot legitimately compete in college, they must take BS courses such as "black studies" and sociology nonsense. These courses cater to purported black grievances and have created a black "educated class" of whiners and malcontents.
When whites defend themselves against black criminals, they run the very real risk of criminal sanctions, just like what happened to George Zimmerman. Inter-racial crime, including rape, murder and battery, is almost exclusively black on white. I predict that when whites become a minority in this country, around year 2050 - 60, black on white crime will reach crisis dimensions.
Whites, including jews, are barraged with propaganda that racism causes black related ills. Personally, I have had enough of it.
