I think the issue here is that you seem to be looking farther than "Wheat refuting the legitimacy of the article" when you shouldn't.

I don't think Wheat is claiming he knows that the conclusions drawn are completely wrong, just that the methods used to draw those conclusions are so faulty as to be useless, and so you shouldn't be taking any of those conclusions with any degree of confidence.

EDIT: I.E. since Wheat isn't really making any claims in his post, and is just criticizing the argument, its hard to pin sophistry on him. Yes he does mention the "European" countries at the end, but that seems more of a "here is some other circumstantial evidence that you seem to be ignoring in favor of your own" type of criticism.
