The article attempts to raise our awareness about what we really think about each other versus what we claim to think about each other.

However, it never points out that each of our prejudices, while mainly illogical, are part of an evolutionary advantage - fear of the stranger.

That's what helped keep us in groups, there was US and THEM.

No one today truly appreciates how valuable a toddler was in 10,000 b.c. to a marauder...slave material, works for food, already survived natality, infancy, and now is self mobile yet oh so facile mentally...so, you'd better not be too friendly to strangers, they really might abduct you!

Is that a genetic predisposition to disliking those who aren't like us? Not clear, but worthy of study.

The best part, for me, of the article concerns who is valid marriage material for one's children. Now that tells the tale of US and THEM.

By a wide margin, respondents believe Americans think Muslims are the most likely to engage in terrorism (83 percent). Forty-two percent think Americans would be most concerned about their child dating a Muslim, followed by an atheist (17 percent) and a Mormon (14 percent). A quarter blamed Protestants or other Christian affiliations for a prejudiced society, followed by Muslims (20 percent).

None of this article should astound or surprise. Racism in and of itself is the cause of group formation, therefore it is self replicating.
