Prejudices are interesting things--there are socially acceptable prejudices and socially unacceptable ones. In my lifetime I have seen prejudices based or race and sexual preference shift from being acceptable to being unacceptable--which does not mean they have gone away, it has just shifted them into the shadows of polite society. prejudice due to someone's lack of religion is still an acceptable form or prejudice. One test is that one can succeed as a black candidate or a gay candidate, but openly atheist candidates pretty much have no chance. It is also acceptable to be prejudiced against polyamorous folk in a similar way that it used to be acceptable for a guy to fear his gay guy friend would hit on him. Another one I have experienced--I often play in bars--is against older men. I sit at a bar and say hi to the person next to me--if it is a young woman, you would be amazed at how often they will turn to their friend and say something like, "ooh, creepy". Seemingly open, liberal women who identify themselves as feminists will pretty much always defend these women, saying they have a reason, it is justified. Well, growing up in the south, folks who will not hire blacks will always say it is not because of their prejudice, but because of some past experience--someone did not show up for work, so they are justified. Anyone experience other forms of socially acceptable prejudices?
