As stupid as they sound, the guys who yell dumbass phrases after the ball has been struck do not bother me, at least not that much. Just before or during the swing is a problem, there is a difference between being a dumbass and heckling. Hecklers should be kicked out, dumbasses not so much, although I think they could be pointed out and talked to or given a stern warning. I mean do you really kick someone out of an event for yelling bobbaboey, after a tee ball?
When I go to a PGA event I want to enjoy the tournament, with a mix of following a group or two, finding a good spot to sit and watch the action, and enjoying a brat/beer. I don't want to deal with hecklers or dumbasses, so I would avoid them.....luckily I've had no experience with either!
