I think that all these people who argue with Simon are annoying. Now I do agree that if he is critizing your looks, clothes or weight then maybe just smile and let it go.....but when he is saying what he found wrong with your preformance --- then listen to the man for goodness sake.
Telling him he is wrong and doesn't know what he is talking about is extreme arrogance. I am going to bet that none of these people have as much experience as any of these 3 judges.
Randy and Paula should be thankful to Simon for letting them be the good guys all the time.
