There is something of the Hellflire and damnation sermon about that original post. Kicking an easy target - child molestors - has a bit too much "justifiable anger" in it for my liking. It reminds me a bit of the way in which films manipulate you into hating the bad guys so much that they simply deserve any horribly violent fate, which they ultimately endure. Child molestors have become our society's orcs. They "deserve" to be annhilated - so we can feel OK about carrying out our revenge/violence/humiliation fantasies on them. In one of his novels, Tom Sharpe pointed out that the old Hellfire and damnation preachers, who preached against sins of the flesh, both gratified the women and excited the men.
Had there been a serious post here on what society might do about the abuse of children, I think there would have been a good Mudcat discussion on the subject. As it is, the sheer amount of gratification that 282RA is taking in the humiliation of offenders strikes me as being pretty close to the "pleasure" that was given to the audience at public hangings.
