If you think there are haters for MK, you should look up info on Karl Lagerfeld - but the hate for him is justified. He is an elitist nasty @-hole. I don't keep up with celebrity stuff much and I've never seen Project Runway - but from the minimal amount I know of MK, I always thought he was a pretty nice guy.
But people go nuts on these reality shows, so don't pay too much attention to that.
