There's nothing wrong at all with your beliefs Owls Fan. It's when you preach about it that it becomes sanctimonious in my eyes.
It's like you're trying to put yourself on a pedestal because you wouldn't dream of leaving a few minutes early when your team is having a bad day. The fact that you wouldn't doesn't make you any better than someone who would in my eyes (assuming the fact that they are regular attendees and not day trippers of course).
