The only thing Townsend's article convinces me of, is that Townsend, intentionally or unintentionally, makes few to any moral distinctions about surfing the net to view pornography. Sometimes he distinguishes between types of pornography (hard/soft, adult/child), sometimes he doesn't. Sometimes he distinguishes between porn consumers and what he terms "vigilantes". As I read through it, he seems to be making a case for these self-appointed "vigilantes" to visit pornography websites (which is the defense he is claiming in his own case), despite the illegality of those acts under current UK law.
I'm with his friend Elton John on this (who was asked about it at the American Music Awards). Based on the story Townsend has given to the press, the circumstances don't look good for Pete right now.
