OK, maybe not love, but at least lust. We tend to take a very narrow time view of a few hundred years. However I can't but imagine in the US in two or three hundred years it will become increasingly harder to tell races apart.
Look at countries like Brazil. Look at the amount of interracial marriage going on right now in the US as opposed to 50 years ago. That I suspect is the future and I don't know how racism survives it.
So instead of various diverse races you prefer a single mass of people with no distinct race?
It's happened all throughout history before. In fact, I'm guessing most members of stormfront might be a bit surprised if they had a DNA test done.
