Getting to the nuts of the bolts: Are white people mean to black co-workers? And why don't white men marry black women?

The vast majority of Earth's population doesn't find black women attractive.
Whether you like it or not - the skin whitening industry is valued at around 10 bln worldwide, while the blackening one doesn't exist or is used as a mockery.

No, they’re not, generally speaking.

As a white man I find many black women sexually attractive as well as personality wise, having said that, as much as we want to pretend that love is enough, it’s not, there are deep rooted cultural differences that make interracial relationships difficult, not saying they’re not possible, they absolutely are, but imo relationships are hard enough with those of similar race, background, demographic, eduction….., adding hundreds/thousands of years of cultural contrast to a relationship is something that will bubble to the surface in time, for better or worse.
Another thing to consider is friends and family, how will they feel about it, how will they treat your partner, it’s easy to hope for the best but many people, black or white hold strong closeted or in some cases not so closeted biases towards those of a different race and that makes it difficult for the two people sharing in the relationship.
Friends and family can be a serious bitch…

There are very black women I find attractive and most of us know the importance of sticking to our own kind.

Getting to the nuts and bolts what does any of this have to do with Trump??

White men typically marry white and Asian women, but they tend to have options across the board.

You should really reverse this question and ask why Black women aren’t marrying anyone.

Those aren't the questions you should be asking. What you should be asking are these two questions:

1.) Are black people more racist than white people?

2.) Why are black women trying to marry white men far more than black men?

First, your username is dismal and dreary. What a divisive, nonsensical question you pose, but I'll play.

The "nut" is you and I'm fittin' to "bolt."
