I have friends who are Hippie Earth Mother types. They tend to have in common a reflexive hate for non-hippie things, such as guns, nuclear power, genetically modified foods, and gasoline engines. It’s always something. Many of my programming geek friends have in common a reflexive love of Unix or a hatred of anything Microsoft.
To me, people with reflexive hates — or loves — just seem to beg for teasing, an education that certainty is dangerous, and that it’s good to not take things too seriously. (The education comes from repeatedly whacking someone’s sensitive spot and ducking, so it’s risky work.) Hot buttons one can’t be teased about lead to ugly territory: hurt feelings, broken jaws, bombs. I think it’s important to tease the deadly serious, is what I’m saying.
So I tease my Hippie Earth Mother friends that gasoline is solar power!
