I'd like to think that I'm not racist but...
I do have a thing for tall, strong, blonde white women. I think a lot of this thing of people generally sticking to their own race for marriage partners, and having friends with a lot of similarities, has to do with promoting or propagating the genes of another person whose genetics is similar to one's own, as well as one's own genes.
When I was in high school I attended an academic competition between schools. The other schools in our area put up reasonably difficult competition. However, I saw some of the teams from Detroit competing against each other and I was appalled at how poorly they were performing. These students happened to be black, and since then it has crossed my mind that they might have been underperforming deliberately as a way to fit in with each other, or possibly to "stick it to the man" but in fact they were really sticking it to themselves. I'm glad Obama said that students need to pay attention to their teachers and do better in school. This is something that needed to be said, and maybe the message wouldn't seem as credible for the black students if a white man had said it.
As far as "ret*d" or disabled people: I feel awkward not knowing how to treat them or what they might expect of me, even though I have been called "ret*d" and there are a lot of disabled people where I exercise. I might just see them as normal people if I got to know them better, but I have enough trouble even relating to "normal" people. It has taken me a lot of time to adjust to physical changes that have happened to people in my own family, but in time I did.
