Everybody's got them. What is the one preconceived notion that you've held on to that bothers you the most?
(Sorry if this is miscategorized. I was looking for some topic along the lines of "ethics" )
Arrogant stupid people is the one group that I am truly prejudice against and My preconceived notion is that they are incurable. This has lead to me having no patience in dealing with them and a burning but controlled desire to beat the stupid out of them; although logic dictates that the brain damage I would inflict would only make them stupider.
But is this really a prejudice? To my mind to be prejudiced against a person or group is to dislike them without good reason. There are plenty of good reasons to dislike arrogant stupid people.
