Is there any large metropolitan area anywhere where that isn't true?
Yeah. Detroit, Baltimore and Memphis, for example.
Are you saying there weren't/aren't majority black neighborhoods/cities?
There were for a short period in two cities, but that's it.
I agree in principle. What is the required percentage? That's what you're getting at right
Percentage is a major contributing factor but it's also the way that percentage is presented and distributed. Chicago for example is 33% which is a pretty healthy number but on the lower end still. However, Chicago being segregated helps raise the presentation of the 33% to being more culturally relevant than if the same number was scattered about. Also it's 33% of a city of 5 million, so it's a lot of black folk anyway. Dallas is 1 out of 4 (25%) and it's also segregated which factors in.
SFBA as a whole is 6% black AND integrated on top of that. So culturally it's extremely weak in comparison, even if you could compare the raw numbers.
You haven't provided any receipts for any of this.
You want me to @ the posters individually? Lol, they know who they are.
