"they never evolved to possess the same enzyme" ... what? Asians are the same species as every other race. The idea that Asians somehow did not evolve this particular thing has nothing to do with the genetic change over time that causes speciation/evolution. I think you grossly misunderstand evolution and that your remarks are ignorant (and I think many people would claim racist).

Nice use of the R-bomb there. And adroit use of weasel words ("some would claim") to give plausible deniability. Unfortunately your objections make no sense. It's well established that some human subgroups have different physical adaptations (eg. lactase production) that have been naturally selected in the presence of local food sources or production methods. How is that unrelated to evolution?

  What is your point exactly? The article you link to states that the flush reaction is genetic, "appears to have been positively selected in the past" and has been hypothesized to "have conferred protection agains certain parasitic infections."

There are evolutionary differences between the races, and the fear of sounding racist makes people say thinks that are untrue scientifically. Example: When exposed to the sun, white people have a higher risk to get a skin cancer than black people (especially if they live in Australia). On the other hand, black people having a skin that filter more UV and make them more vulnerable to a Vitamin D deficiency (especially if they live in NYC). This is simply because they evolved to adapt to different climates. Just claiming "no, there is no difference because we're all the same species" is plain wrong.
