I hope this doesn't sound stupid, but do you believe that there may be a genetic influence on politics?
I was recently talking to a group of hippie-ish vegetarian girls. We got to talking about the election and politics and unsurprisingly they were all liberal. So hippie vegetarians being liberal is not that interesting, but what I also noticed was that they have vegetarian teeth. Their canine teeth (fangs) are rounded out and not very good for tearing through meat. Their incisors and molars are kind of flat, and useful for chewing tomatoes.
The structure of their teeth in theory would influence their diet, but should influence their political leanings. However, from experience they're related. I'm not claiming that vegetarian teeth are the cause of liberalism, but since they're correlated, maybe there is an underlying genetic factor that cause both (?) What are your takes on this?
