Idk where you live but in 'my' reality it's the exact opposite. The Black men breeding with white girls are the epitome of self-loathing and try to be white dudes in Black skin (ie, 'I'm not like THOSE people'). They teach their kids (ESPECIALLY girl children) that they are not Black and to stay away from Black culture as much as possible. And those men and their white wives/BM encourage their children to be called anything and everything but Black. And I know a lot of Black men that feel this way, as opposed to one (literally, one) Black woman that ended up with a white man and calls her son mixed. I don't know any other Black women irl that ended up with white men and encourage their children to be anything but Black. I hardly know any BW that even date BM but I can name at least five BM I know off top that date white girls and hate their Blackness.
EDIT: For example, my best friend's uncle married a white girl and had two sons that he refuses to call Black. He encourages them to refer to themselves as mixed and biracial and distances them from Black culture. He does not visit his family with the kids and will only take them to visit her family in Colorado. He doesn't let the boys watch tv or listen to hip-hop or play basketball, he ONLY lets them play hockey. It's a real mind fukk to observe. My boss is the exact same way, Black ass dude that married this fat white chick and will only let people refer to his son as mixed or a half-breed. (Literally his words, 'half breed.') In my reality there are far more Black men breeding out to make non-Black children and saying it explicitly than Black women.
