I agree with the idea of a new "exotical" class of blacks. People that get the benefits of being black without any of the drawbacks and they pro-create and marry within their complexion. The new Paper Bag Society.
As far as why the athlete brehs marry white? I don't think there's any deep logic to it. Think about it....most decent looking top-athlete brehs go to mixed or predominantly black high schools. They date the best looking sistas at their school (if they have any kind of game). Next step, they get recruited by top colleges....schools that are 80% white.

You get the best looking white broads coming onto you without being prompted. Most sistas, especially in high school, won't just come up to you for no reason unless you spit a little game first. 20-year old white girls will throw themselves at any breh that looks like he's got a future in the NFL, NBA, MLB etc. White girl already thinks the breh is attractive, but she's not going to make that move unle$$ it'$ worth it. $he could easily marry some white boy simp making good money at Pricewaterhouse Coopers or Morgan Stanley. However, if the choice is between that and a yoked up breh with 10x as much money, it's an easy choice.
To me it's not the race....it's the thought process. Black athletes that marry white girls need to make sure they marry someone that has actually considered what it means to raise black children and deal with the world through a black lens. If she says some shyt like "I never thought I'd end up with a black man", that's a problem. It means she never really considered a black man that was her equal. She only got on the black train when she realized she could pull a top 1% breh. Most of these athletes date white broads that wouldn't know the difference between kale and collard greens.
