I don't remember mmkunming writing anything about race at all, much less about any conceptual absurdities of racial purity.

@mmkunming: I know what you're on about, but I still think the term 'cultural colonialism' to describe the attitudes of numerous foreigners in Kunming is misplaced. Colonialism, I think, implies either the possibility or the reality of taking over, and foreigners in Kunming are in no position to do so. I've suggested 'cultural arrogance', which I think is sufficiently descriptive and sufficiently annoying and obviously present (and not only among foreigners, but that's irrelevant, unless one has some 'THEY do it so we should too' type of attitude). 'Willful cultural ignorance', which likely leads to cultural arrogance, might be another one - the elimination of such ignorance requiring learning through experience, not just some kind of academic thing.
Ruling groups, in government, massive private corporations, the media, are of course all about cultural hegemony, and always have been - these people can back up their efforts with law, cops, education, money, tourist sites and museums etc., and do so in their own interests. Very frequently nationalistic. Some call this progress, even some kind of social evolutionary progress - I have my doubts - but all indisputably involved in cultural change (as is the groundroot resistance & necessary adaptation that rises from below).
I also think it's worthwhile to consider the concept of expat culture, a kind of offshoot of globalizing culture which is not necessarily monolithic and not necessarily 'good' or 'bad' and which develops in some autonomy from national cultures, including both the one that surrounds it ('Chinese', here) and the ones from which its members originate, has its own internal conflicts, compromises & cross-fertilization, within which, thanks to numerous accidents of history, the English language might be considered to represent cultural colonialism, as it tends to dominate expat communities...hey, I can go on like this.

@I think the difference between salary, ideally actually earned through socially useful labor, and income, which might come from almost anywhere in exchange for little or nothing on the part of the one getting the income, is one that more people should try to understand.

I doubt if mmkunming would put the Brother Jiang in the same category with 5-star restaurants. I think he's on a mission to try to get people to 1. understand that there are things they don't know (necessary 1st step) about food, and that 2. they might try to do something about it.
Having said that, I'm a slow learner, though even I have discovered a few things through experience. You can, too.

@right, Magnifico, quackery - just like the stone-cold musical equality between music produced by guys who can play chopsticks on a piano and those who can play Mozart. This doesn't mean you have to like Mozart, even after hearing it a thousand times, but it may indicate to you that you may be missing something.

@Kate: Well, all that seems to make sense to me, though I can't really do any of these things. But I'm certainly persuaded to try anything that anybody produces on the basis of consideration of these principles - beats the hell out of some unconsidered positive reaction to, say, sugar - ants can do that.
