I've got no issue with it, to be honest until this thread I never even thought much about it, same goes for all other racially diverse couples.
Would I date an Asian myself? Sure, I don't see why not, she'd just have to be the right one for me, at this point I have no idea who that is.
I think it's strange that some people do make such a big deal out of race as if it's an evil thing to be dating someone that's not "of your kind", makes no sense to me.
