Ever since the Subway guy was arrested for child porn, I've seen a plethora of jokes about "foot longs" in prison. I know they're only jokes, and I admit I do find them amusing. But if you think about it, this is a rather sad statement about our prison system, and our society.
First, the flippant reference to the prevalence of prison rape is an acknowledgement that an American prison is little better than a sanitized version of a medieval dungeon. We may not have red hot pokers and thumb screws, but sexual torture is still common place.
Second, imagine if there were an abundance of jokes about how Jodi Arias was going to be repeatedly raped in prison. Regardless of whether or not she is a “bad person”, would we all be laughing about that? I doubt it. So why do we laugh about a man being repeatedly raped in prison?
