And, for a not-over-the-top and insane comment, they're fundies. They can't accept anything outside their own worldview. Because of that, an exercise routine, especially one with roots in another religion, from another culture, is something that's going to freak them out. What I find amazing is that fundies don't kill themselves due to living in CA. You aren't going to find a more diverse state, with more diverse cities, elsewhere. You've also got all those celebrities who, for the most part, are crazier than a bag of cats.
