@blatham,
blatham, thanks for taking the time to explain.
Yes, the Catholic part I knew something about. Yes, I think I would see a catholic voting for a catholic partially because they were catholic as partially bigoted. Having said that, all other things being equal, I'd vote for an atheist over a religious person and not see that as bigotry (although I'm sure everyone else would think it was!)
Now, you say that I make the claim that a black voting for Obama in part because he is black is an instance of racism. I do. The test for me is to view it in negative. If a white is voting for McCain in part because he is white, it's much more obviously racism.
I have a pretty good grasp of the concept of positive racism. I'm uncomfortable with it because it reinforces the notion that skin colour is important. I think "bootstrapping" programmes should be designed to help those who need it, on the basis of need rather than colour or bloodline or heritage. It seems somewhat paternalistic and condescending, a byproduct of white guilt. The sooner everyone drops the notion of "race" and starts seeing themselves and each other as human beings, the better.
Now, I know I'm being overly idealistic and more than a little naive. There are things that should be compensated for, there have been generations of oppression that create poverty traps and negative sub-cultures that ensure that a "level playing field" is anything but fair.
Never-the-less, I can't let go of the deep conviction that skin colour prejudice of any kind is way past it's expiry date.
I'll check out the Gang of Five, maybe it'll change my view, or at least I'll be a little less naive.
