Well, I'll never tell another 'fan' how to root for their team. Do as you please, it's your right.
But I will call a 'tanker' a 'tanker'.
I will also continue to be disgusted by those who want the team to lose (i.e. a 'tanker').
See, I think this attitude is nothing but detrimental to discussion. Discussion, after all, is what these forums are supposed to be for.
It is your right to find arguments that prioritize the future at the expense of the present distasteful. It's your prerogative to feel that the Celtics organization owes their fans a good product on the floor every season.
But I think "disgust" is taking it too far. And by refusing to shed the "tanker" label, you're refusing to acknowledge that the positions you disagree with are based on reasonable beliefs, even though you disagree with them.
I have a problem with that attitude.
