This should be alarming, right?

I am more concerned about this:

A prisoner was banned from playing D&D due to the same stupid hysteria that descended in the 80's.

Aside rights issue, it depends on if his conviction is at the federal level or not. If he's got a federal felony (I'm not sure on state level felonies, although most follow the federal lead on rights), he has no rights. The first thing that happens to anyone that commits a felony at the federal level is your rights are revoked. They are only returned to you if you petition the government after release to have them restored (I know of no one that has successfully petitioned and won) or 20 years have elapsed since you finished your term. So, without knowing for sure if he has a state felony or a federal felony (although most states also suspend rights upon a felony conviction, but petitioning a state to get your rights back happens fairly frequently), he has no rights thus the prison isn't infringing on his first and fourteenth rights (cause they're suspended while he's in prison).
