You thought he was good? David Icke? Jesus.
You've not read anything by him, but you went to see him at Brixton Academy? hmm 'kay.
Me and the missus enjoy watching the odd Icke DVD, she's a scholar of mythology, esp. goddess mythology, man can she point out the constant bullshit. It's not just that his conclusions are delusional but that his facts are often wrong. He's a self-publicist, liar and snake oil peddler. Probably the worst out there, and you think he's very good.
I suggest you look out for John Ronson's programme about him. It's revealing. In fact, as your such an academic of this stuff you've probably no doubt seen his series called 'Secret Rulers of the World'?
