I have a different view in this. I think a lot of people don't fight an opposing tribe, they fight the world, and thus if you are not in the tribe, you are in the world, and as such problematic. Two examples. I know a very conservative guy who really likes Rene Guenon and thinks the whole modern world is rotten. I also know a Marxist who thinks every tradition is a legacy of oppression and injustice of past times, so almost everything should be deleted and started anew. These people, from opposite angles, oppose most of what exists. This is what I mean by fighting the world. Since they fight the world, they are correct assuming that if you are not an ally in it, you are more or less an opponent.
