What is racism?

[Scrooge McSam]

I don't think noticing or even pointing out differences in races is necessarily bad.

The troubling thing is, more often than not, this examination does not lead to a celebration of differences and chance to learn from them, but rather a way to slice and dice the population in a bid to divide and conquer.

Next you start getting the argument "Why should my taxes be used to pay for XX, an obvious weakness in the XX race".
