The whole concept of "race" is on pretty thin ice to begin with. Applying the word to the Dutch isn't necessarily any more or less meaningful than to, say, all Chinese -- it's something that's socially constructed.

Ah, you are correct, to my embarrassment. I immediately associated 'Caucasian' with 'Dutch'. But there may be non-Caucasian Dutch as well as non-Mongolian Chinese. Thank you.

And non-Dutch Caucasians, for that matter.
