Fleche, I disagree with that on a couple of levels. But let's start with the easy one.
I don't think you can be a strong supporter of the football program without some cognitive dissonance. Everything Joe did was about keeping that football program a national power. You can't take pride in where they are now unless you basically ignore that they more or less got away with covering up a serial child molester's actions. So I wouldn't do this, but I think you can at least make a case for separating the football program from the school as a whole. You can be a proud alum, but I don't see how you could condemn Joe and still be a proud football booster.
But I wouldn't even separate the two, and this is the tougher putt. To me, PSU's entire culture is wrapped around the legend of St. Paterno. IMO, that's how the frat hazing death happened, and why in its aftermath, many students openly flouted increased regulations. The culture there isn't about doing the right thing, but about the way they want to do things -- and doing as little as possible to change. In the wake of the death, PSU put in new regulations, but they did what was minimally adequate, and as I said, many students there were still pissed off about it. What they really want there is to be left to their own devices. And until someone in leadership stands up and says "enough," that will always be PSU's culture.
So to be a proud PSU alum is to be proud of that culture. And that culture, stoked by Paterno and all of his fans for decades, is fucking rotten to the core.
You don't have to draw any conclusions about RU to condemn what Ray did. That makes it a lot easier, emotionally.
