*Black guys, if this doesn't apply to you then don't be offended. Just an observation.*

Short answer: racism. This happens with white people too honestly, like it can be more acceptable for a white guy to date a black girl than for a white girl to date a black guy.
I think it might have to do with how men subconsciously compete with each other about women. So guys would rather have their own race date their own race, instead of "giving" them to another race. But they dont have a problem with taking girls from another race because its almost like a competition. Anyway its incredibly hypocritical, and its based on slight racism. You should ask your dad why he thinks its fine for your brother to date a white girl, but its not ok for you to date a white guy.2

This is why I am just problack-woman. It's about to get much deeper than this question, haha. There is so much hypocrisy that comes with black men. They complain about being murdered and stereotyped but then they go back around and worship music that promotes those categories. They complain about white people being racist against them, but yet they go back and either accuse white people of racism before they get to know them or are racist against the white person without even realizing it. With this topic, I think it's just a matter of black men wanting what white men have. There's always been the case of black men feeling inferior to white men and they try to "get back" at white men in any way possible. White men praise white women? Black men do the same. A black girl could live next door to a black man, the black man won't pay any attention to her but once a white man gets her the black man will want her too. I guess they just see it as, if they can imitate white men then they can replace them and be superior. That's all I get from instances like this.2
