I've been wondering for a long time if evolutionists are, for the most part, left wing liberals who are just as arrogant and close minded in their thinking of the origin of life as they are politically.
No, evolutionists are those to hold the position that the theory of evolution is the best and most accurate explanation of the history and diversity of life on Earth - which happens to be the position supported by the evidence.
I'm aware of many, many right-wing evolutionists. If you're referring to biologists, on the other hand, it is generally true that, like every academic community, they lean heavily left-wing. This probably has something to do with the right-wing generally dismissing the work of teachers, professors, librarians, and other academics for decades. No surprise then to see them poorly represented among educators.
