Big personalities are one thing. Calling people idiots because they may not know as much about a topic (as happened not that long ago to Sara) is the epitome (tome, heh heh) of elitism. The message is often "I know more than you do, so either shut up or go away". I started a thread on key racing skills that was immediately parodied. My thread ended up with several pages of what many considered to be valuable information. Someone less persistent than I am would have just gone away, or never bothered to start the thread and risk the ridicule.
