@chai2,
My first impression of the article is that it's a grab bag of superficial stereotypes. They remind me of statements like "Black people got rhythm and talk articulately", "Jews are good with money", "Capricorns are hard-working, loyal family people, though slighly boring", and so forth. Maybe I would find the claims in the article more persuasive if they had come with evidence to back them up. But they did not.
