I don't believe in miscegenation. I think people should love and honor their own culture by sticking with their own. I don't think anyone's going to hell for it, and I wouldn't go so far as to legally ban it, but that doesn't mean I have to like it or think it's right. I have very strong negative feelings about this topic.
In a way, i agree...people of similar cultures are less likely to find conflict in their marraiges...i mean, it's not just religion.
However, as long as they are the same religion, if a man and a woman love each other and will make way for a loving household, irregardless of race or culture, it really ought not make a difference. Likewise, some people are attracted to certain physical being...so i say, live and let live.
Now, within that whole mess, there are exceptions...so I'll simply say, a good thing is when you have a man and a woman from the same religion who love each other and are righteous on equal levels. (In other words, a rightreous person should never get with a non compatible evil person) Or a great guy shoudl not go with a girl with a questionable life history background.
