First let me say I think you are rational and sane.
However I completely disagree with your stance on this lunatic being a "vocal minority". I'm sorry to say for you, who at least have reasonable thought processes, that you school/alum are infested with people like this. You make it sound like he is one of 5% of your fans. He may be the extreme, but there are TONS of his ilk. Maybe not as many people who think Sandusky wasn't so bad. But tons who feel that dirtbag Paterno was a saint, and tons who feel this has nothing to with football , and tons who cut off their right nut to have the Paterno statue restored.
And you are right, it makes your school look horrible. And this is not a "Rutgers jealousy" phenomenon either.
Unfortunately, there are people on both sides of the fence who really don't know the facts about the situation. My parents are nearly 80 and were appalled when I first told them my feelings about the whole situation and Joe Paterno. After talking with them a bit and asking questions, it was clear that they had no idea what they were talking about. I truly believe there are a lot of folks who are like that and just want to hold on to Paterno as being some type of idol. I've had a few (I try not to even get going) conversations at games and the same is true. The logical progression is that Joe Paterno did what he was supposed to do, the higher ups dropped the ball and the BOT used Paterno as a scapegoat. Legally, I suppose most of that is true. That still leaves us with that email though. Even then, the email is subject to interpretation at this point.
