There is no doubt that racism and prejudice exists in all ethnic groups in America, and this poll will be used for political and personal gains.
In my opinion, these tests and conclusions couldn't be more biased than I ever could have imagined. Many of the questions are constructed in such a way that it would be very easy for a person to give answers that supports the author's conclusion. I think most here would agree that many people do not have the best reading comprehension and some/most are terrible test takers. Then comes the interpretation of the answers. I guess they can really read our minds.
And implicit racism? Implied though not plainly expressed: a belief that race is the primary determinant of human traits and capacities and that racial differences produce an inherent superiority of a particular race. Sounds a bit inflammatory, doesn't it?
Racism is ugly and so is anyone's conclusion based on their own (implicit or otherwise) motives and prejudices.
