For me rules and boundaries have meaning. Rules provide structure, stability and consistency. The people I'm least likely to get along with are liberal or artistic people who see the world as fluid and feel that fewer rules are better. For me, this is disturbing because I'm unable to follow the concept of everyone doing things differently. I simply cannot connect with these people.
While I'm like you in that I cannot get along with those kinds of people, I've also found I cannot get along with fundamentalists, or people who make gray issues into black/white. I consider myself a moderate conservative. I like logical consistency, but with some room for abstraction and mystery. Religiously, on the conservative end, this would be more like the Lutheran Church Missouri Synod, rather than IFB, CREC, Vision Forum, or the Gothardites. Politically, it's more like the Solidarity party, or libertarianism, rather than Calvinist postmillennialism or anything the modern evangelicals have been putting out since the 1980s.
