A mixture of reasons:
- its not even remotely as common as users here and elsewhere make it out to be
- if they do like blacks its because they have a niche fetish for it
- blacks are oppressed (in their minds) and so having sex with one is making up for it but the black guy essentially becomes a toy
Because black men are superior. If white women didn't have to fear getting murdered by insecure white males at least 60% of all white women would never date, fuck or procreate with a white man. Problem is white women are living in fear because the white man is the most insecure, sensitive bitch made punk cuck known to man. They will use violence on them and their black boyfriend's as history has shown.
That's ok tho because they'll be extinct by 2032 after the revolution.
The answer is to actively promote BBC/BC to white girls. When you see how big the BNWO movement is growing, many white guys are choosing to become cucked by the black race, and enjoying the tantilizing results.. no doubt Blacked, BlackedRaw, Black on Blondes has contributed to it and their next level porn directing.
