I think people need to have a bit more of a global perspective on this than just country. White people are a small minority of the world population. I'm white myself, but I very much enjoy spending time with friends who aren't. They are human beings. Race is very superficial when you look at human DNA. I enjoy travelling to other countries and meeting people from all over the world. Why not? They are very interesting. Who doesn't like geography??
I'll be honest and say that I'm usually only sexually attracted to white people cause they look like me, but not always. I just think it seems narrow minded to block yourself away from potentially great friends, etc just cause they are not the same race as you.
