Are you sure that's what the parent post meant?

I don't agree that they have been "ethnically cleansed." I'm sure economics has forced some out.

I've live in many parts of the country, and this is by far the least racist, and most racially diverse, place I've lived.

Black men in the city would be expected to have a lower life span than black men nationwide, since urban black neighborhood are more prone to drugs and gangs. Have you compared to other big cities, as opposed to just nationwide?

I once took a Uber ride with an African-American gentleman as the driver. He had previously been a policeman in the SFPD, and his uncle owned a print shop in the Western Addition. He refused to sell his shop when Justin Herman's "renewal" project started. Shortly after, persons unknown vandalized and destroyed the print shop at night.

Ok, well that was over 50 years ago. A lot has changed since. Currently San Francisco is one of the most diverse and liberal large cities in the country. The black population is certainly lower than various surrounding cities such as Oakland, but that doesn't mean it's mostly white.

I just looked at a few lists of the most racially diverse cities in the U.S. and SF doesn't make any of those lists.

San Francisco also has a disproportionately low amount of black folks living there.
