"They're a very musical people, aren't they?"
Second, I'll say "who cares?"! :))) No one is going to take someone trying to boil the races down to their various "usefulnesses" as a helpful thing. I see you want to contribute in a positive meaningful way, and I shouldn't just put that down.
Ultimately, there is huge friction because of the differences in the races. Are you just ignoring that friction and instead saying "let's celebrate our differences"? Isn't that just muliculturalism?
What about the really hard stuff? Like that jews have won more nobel prizes and cured more diseases per capita than anyone else? Or that the British invent a huge amount of stuff? But if you comment on those things, isn't everyone else going to be put out that you're saying they aren't as smart? Or what if you say that black people are good at athletics? Isn't everyone else going to be put out by that? Maybe some things are just best left alone?
Have you studied some of the existing scientific theory of the races? Eg http://en.wikipedia.org/wiki/Mongoloid
I still say if you're going to deal virtually exclusively with racial issues, you should buy a different $5 domain name
