I'm not against them, however..
Two of my cousins are married to black men and my uncle has had a shit fit about it from day 1 in both cases. He hates the husbands, has little to do with my cousins and treats their children like shit.
His reason? "(black people) are worthless. They'd rather steal from/rape/murder white people than to look at them. You can do better."
Unfortunately, one of the husbands really is worthless. Of the ~15 years he and my cousin have been married, he's spent ~6 of them in prison and he's been in city and county jails regularly. He uses and sells hard drugs. He's emotionally and physically abusive to my cousin and their kids. He has cheated on my cousin more times that I can remember. He's just an incredibly scummy individual.
My uncle, of course, takes this as proof of his belief. He can only do this because he disregards the fact that my other cousin is very happily married to a truly great guy who helps provide for his family and would do anything for my cousin or the kids (half of whom aren't even his biologically). My uncle says that he just hasn't shown his true colors yet. He's freaking 40+ years old. If he hasn't "shown them" by now, then what you're seeing probably ARE his true colors, asshat.
