This will probably go down like a lead balloon but from what I see this forum seems to be descending more and more into a homogeneous drama queen mentality. If all he has done (wasn't at the game so can only go off above comments) is boo a side that I think most would agree is under preforming I don't see the problem. He is helping fund what is allegedly a top 10 budget so he is quite entitled to be disappointed if results don't reflect this. In regards to walking to the half way line to berate the ref, how many can honestly say they have never done something similar, I know I have.
I can't believe people are taking about banning him from coaches or even matches, really, who do you think you are. If he is causing physical harm to people then yes this is an issue, but it is not your issue there is something called a legal system to deal with this.
Don't get me wrong I love positivity and harmony but I love freedom and individuality more.
