Why don't Chaldean(Catholic Iraqi-Americans) let their daughters date White men......?

If you are Catholic also, than it is definitely racist. Some people are just uncomfortable with interaccial dating, and it isn't limited to any one group. You find a hard*** in every culture, and if they are bigotted, I say the children are the first ones who should break that stupid tradition by marrying anyway. I know plenty of people who went interracial against parental wishes and the parents dealt with it in the end.
