I think it's really easy to complain about the team, its just the easier path. It takes time and effort to see the good with the bad, you actually got to spend a very considerable amount of time and effort.
You can't change these people's view because they just don't put any effort into being a fan, but they still wan't to be heard. if you challenge them they will disappear and reappear at thier earliest convenience.
But Some of these fans are quite atrocious, are these sayings dead? "if you have nothing nice to say, say nothing at all" or "The grass isn't always Greener on the other side" and my all time favorite “If you don’t like something change it; if you can’t change it, change the way you think about it.”
But in the end, we are who we choose to be. If these people want to get worked up over molehills, theres not much we can do about it.
It would be a shame to see you leave these boards, you are so many things to us. But another quote comes to mind "Anything that costs your peace is too expensive" so maybe the ignore button could sooth your soul.
Take Care.
