Are people who dont answer questions seriouly illiterate of just brain dead.Who makes your list?

There are a a lot of people who use sites like these to get real help or advice. Some users (who answer questions at times) are just mean, have no respect or regard for others. They always give answers that are distastefully funny or plain insulting. My top most annoying user who continues to do that - MIke J...who is yours...I cant think of any other right now. Why do some people CHOOSE to be so disgusting and annoying. I'm sure even with this question, you will see some perfect examples. Idiot to the power of 10
