This question doesn't make any sense? There is a lot of white women that marry black men. I'm a prime example.
(1) it depends on the region of the country. In large urban areas and in the western part of the country you will find more interracial marriage then in the midwest and the south.
(2) It depends on the woman. Different women like different types of guys. Just like men. Different men like different types of women. Not all men like same type of women.
(3) Also it is a handed down generation belief. Most "baby boomer" white women are not into interracial marriage. However, a large percentage of white women of " Gen X, and younger are into interracial marriage.
(4) YOUR ATTITUDE ON HOW YOU APPROACH THEM!
Don't approach white women with a "Getto" mentality and "Getto" appearance!!
Note: I live here in Las Vegas Nevada (Interracial marriage mecca of country) and there is a lot of white women that "Love" black men! As well as Asian, Latino, European, and black. Young and old.
So it depends on the region, the woman, their generation, and your mentality!
