The interaction between black people and gay people is my favorite politically incorrect topic.
A bit of background is necessary. In previous decades, blacks kicked white people out of – what are now called – "historic black neighborhoods." These neighborhoods are generally neighborhoods close to the center of large cities. In recent decades, gays have begun kicking blacks out of these neighborhoods.
The "kicking out" processes are interesting. Blacks kicked out whites through a combination of increased crime, corrupt politics, and bad schools. Gays kick out blacks through increasing property values and new businesses that cater to people with high levels of disposable income. The latter process is generally referred to as "gentrification."
The final point worth mentioning is that blacks don’t like gays (HT: Richard Spencer, who adds some good thoughts along the same lines). You’re not supposed to discuss this particular point, but it’s very true.
I see this process in action every day, and it makes me very sympathetic to gays.
(Also noteworthy is the this Times article on DC gentrification, which studiously avoids mentioning gays).
