Prejudices against people are very subjective and questioning them is comparable to trying ot catch chickens. I have my own prejudices too, but I do not, or at least try not to force them up on others. What really is annoying about some people with prejudices is they try hard to actually find all the wrong attributes about the thing/person they are prejudiced about and harp about it incessantly. How much does to take to come to terms with the fact that you like or dislike something for no reason and stop picking on some rather senseless trivial issues in a poor attempt at justifying those prejudices.
