Tiger, my post was directed at the collective thousands that streamed out of the ground when it was clear we lost. Of those thousands there'll be some with a very good reason. I've never quite understood why someone can spend 4 hours of an afternoon at the footy, but not 4 hours and 30 minutes, but everyone has their own life to live.
Most won't have a good reason, unless you consider chronic poor sportsmanship a good reason.
You're dead right that you are entitled to leave whenever you like, but as a supporter, when you walk out on your team without a good reason you should be prepared for people to have a crack when, in their view, you discredit the team and the supporter base.
And if you do have a good reason, then what the hell do you care what some bozo like me says on a discussion board?
