I've never been attracted to anyone who isn't white. I've seen some black chicks that I thought "oh, they're cute" but not in a way that I'm attracted to them. Meh.
I can't relate to this mindset in the slightest. It's a sentiment from another planet to me.
And another era -one that is, thankfully, fading.
There's nothing wrong with such thinking.
It's not beneficial for you because you're effectively excluded from a good 25% of women no matter how strong their merits are.
Sexual attraction, at least not for humans, is not a particularly logical impulse. We find ourselves attracted to dark hair, light eyes, small stature, long necks for no reason in particular. Is there a method to such madness? Perhaps. I would not be surprised to find studies proving such things. Until, then however, it can only be said that our views are somewhat shaped by culture, but we all have our personal preferences.
I know many people who are well-traveled, well-informed, and generally intelligent people, who simply aren't attracted to people of different races? Have they not had a wealth of experiences? They have.
