1)The main point, that black women aren't marrying, is another case of when white america sneezes black america ends up catching the full fucking cold; millennials ain't marrying each other neither.

2)The idea that black women are losing black men to interracial marriage. We may date outside of the race more, but that says more about black women's low levels of dating outside of the race PERIOD then a general run away of black men. On top of the fact that interracial marriage in America is pretty low in general

3)Like its been pointed out above the prison industrial complex apparently makes men undateable also. While many of us succumb to the traps in our 20's, our rates of incarceration start to dip in the 30's. By 40 the recidivism rate is really fucking low. It's another reason why society just forgets black men once they've gotten fucked by the system so in addition to getting a job and voting, we can add 'dating' to the list.
