Christopher Hitchens on Censoring Pornography

In an essay on free speechChristopher   Hitchens called the urge to censor pornography a red-herring. He said:

"Other attempts at abridging free expression also come dressed up in superficially attractive packaging. As an example, surely we should forbid child pornography? In a sense this is a red herring: Anybody involved in any way in using children for sex is already prosecutable for a multitude of extremely grave crimes. Free expression doesn’t really come into it. The censor is more likely to prosecute a book like Nabokov’s Lolita and yet have no power to challenge porn czars. And surely the spending of money isn’t a form of free speech, as our Supreme Court has more than once held it is, most recently, as pertaining to political campaign contributions."
