What if he does know more? Just interesting mental experiment. Should only people of a particular race be authorities on matters of their own race? Seems a bit... I dunno... racist to me?

The only thing this guy is guilty of is liking a particular type of food and particular type of women from what I can read, and it's not outside the realm of reason.

Yes, I am a white male that likes Asian cultures, I speak two Asian languages, though I really don't like the food, and many of my exes were Asian. But many also weren't. And having people assume I have some kind of disgusting fetish because I speak the language makes me upset all the time and I walk away from such people immediately. It's not a fetish to prefer something, jeez.
