My father who is from the south was very opposed to it, so my parents didn't attend the wedding, though the rest of us did and had no problem with it.
Though the marriage didn't last long, and she's remarried twice since (both white guys..so much for the "once you go black you never go back" cliche) it opened my eyes up to the degree of opposition against interracial couples.
I had a brother marry a Korean and another married a girl from Guam and my parents initially gave them both problems about it.
However, I've had many, if not mostly black friends during my life and found that there is a lot of opposition to interracial dating and marriage in the black community as well.
I think prefering one's own race is a natural tendency and doesn't necessarily mean that much otherwise.
I think there is a high correlation between white girls who date black guys and the girl having "daddy issues".
I'm white. I dated a guy years ago who was a Puerto Rican from Harlem (but moved to Atlanta). I thought he was Italian when I met him, but had no problem that he was PR. My parents liked him when they met him, also thinking he was Italian. I could see a look of extreme disapproval when my dad found out otherwise. The relationship didn't last (due to the guy being a JERK).
