When you get right down to it, in many parts of Western Washington (Seattle, Bellingham, Olympia), a liberal can very easily never have any contact with a conservative in their daily lives. It is almost impossible for a conservative to not have at least some contact with liberals; kinda like trying to live in Salt Lake City and never interact with a Mormon! The reverse could also be said about many areas in Eastern Washington, although I don't think to quite the same extent. It is, in my opinion, what leads to the "demonization" of people with the opposite political views. Like anything or anybody; immigrants, guns, wild animals, etc., it is a natural tendancy to fear what one doesn't know.
