I think the biggest problem, and this is a People Problem, is that groups of people always seem to have preconceived notions about other groups of people. Wasn't it Alexander Pope who said "a little learning is a dangerous thing"?

For instance, if all someone knew about me was that I have three tattoos, they might automatically assume I own a motorcycle, or that I have a pierced nose. I have neither one. If all they knew about me was that I'm a musician, they might automatically assume that I vote Democrat. Sometimes yes, sometimes no. And if all they knew about me was that I usually vote Libertarian, they might assume that I'm all for drug legalization. Nope.

Perhaps we might try to see people are individuals, rather than members of a group.
