That is one of the things that really irritates me.
To the left, it is a given, an untarnishable, immovable, unchanging, accepted truth that the simple presence of people of different cultures of colors improves things.
Factually, there exists plenty of real-life experience to prove just the opposite. But nope, if you contest that, hey, you are a racist.
One might innocently ask (only to be ignored or shouted down) why there is this movement to have women only areas, black only areas, or hispanic only areas on college campuses...doesn’t the monochromaticity make them LESS useful and LESS desirable places to be?
