We're not allowed to talk about Black culture.
We can talk about generalities and tendencies of other cultures such as the Irish like to drink, Jews are often neurotic and Germans are meticulous. But talking about Blacks, no can do.
I remember a story about a traffic analyst studying methods to relieve congestion in a major city, might have been St. Louis. He spent a long time studying different areas and his report happened to mention low-income (Black) sections of the city tend to have matriarchal families. How that affected traffic I can't remember, but he did get in big trouble for mentioning that one obvious fact in his report.
If you talk to policemen, watch Cops or Live PD you'll quickly learn Blacks have a serious hearing problem. With guns drawn, the cops can command "Show me your hands" ten times with no compliance whatsoever from the suspect. Maybe those buses offering free hearing tests should spend more time in the inner city.
With improved hearing the hope would be that it would lead to a reduction in diarrhea of the mouth. Personally, I have no patience for a stranger who walks up and talks gibberish non-stop, often interspersed with "know-what-I-mean" every 15 seconds. No, I don't know what you mean because you're babbling pure horsesh*t.
Everybody's different and that is a good thing. Talking about those differences and even joking about them shouldn't be a crime. But today, even comedians are not allowed to venture into certain areas because it has become taboo in our society. That's a problem.
