But does this work for other sexual choice communities? I suppose there must have been class divides where "working class" men were more likely to go to jail so changing the sexual choice landscape? Gay men?! Ex-military? Prior to public transport was there geographic boundaries? Education?
This is a fascinating subject - why are black women limiting themselves to a reduced choice of black men when presumably other races are open? What is it that makes that choice / boundaries? Clearly parental type must have a big impact, but what else?
This is an indictment of US post-slavery culture to be sure, but thinking about it it is massively wider in scope.
Any pointers to research on this?
