Hardly surprising though. When I was in high school I don't recall ever hearing the word libertarian. Talking about politics wasn't something we normally did. Only when presidential elections were happening did anyone really talk about politics. And even then it was just to either make fun of someone or say who they would vote for. And really that was only a few obnoxious males.
I just don't see a lot of black, non-white Hispanic, Asian, etc people foaming at the mouth discussing libertarianism. None of them are clinging to their guns and as long as they can go to church on Sunday they don't think a Chanukah display at an airport is taking away their religion.
Ask the average black guy what he thinks of a Chanukah display and he will say it looks pretty and move on with his life. He has no idea he is supposed to be upset and mailing checks to Ron Paul.
