The ironic thing about all of this is that the people who claim to be true fans because they don't criticize the Bills are actually anything but for that same reason.
Real fans do not get excited when their team hires retread coaches and 70+ year old rookie GMs.
Real fans do not say "oh well, let's see how they do" when an owner benches Flutie for Johnson, or the team drafts RBs and DBs over and over in the first round.
Real fans do not tell themselves that the Bills can get to the playoffs when 60% of the starting offensive line hasn't played a down in the NFL and the new OC just got hired a few weeks earlier.
What do real fans do in these scenarios? They whine, complain and B word. Why? Because they care and the dumb things this team continually does actually hurts them. The ones who can get excited about this joke of a franchise just aren't as emotionally invested in the team. And that's okay. They're the same people who will say "oh get a life, it's only a football game" or something to that effect. This mentality has served you well for the last 10 years, I'm sure.
Just know this though: When they finally do win the big one, it'll feel a lot better to the actual real fans than it will to the "why are you so pessimistic?" group.
