While I detest porn as a destructive influence on marriages (and therefore families, communities and ultimately nations), I am also a libertarian. I equally detest big government interference in the free exchange of ideas between adults.
But I’m also a parent, and agree that a duty of authority is to protect the innocent.
But I’m also a Christian, and don’t trust sinful, fallible humans to wield great power unselfishly.
So my considered stand on Internet Censorship is that it’s a slippery slope. While I wish that porn and other destructive influences were not so prevalent, ultimately the responsibility lies in the heart of man. Until we reduce demand, the supply will always be there.
