More nonsense appeals to authority.

The most authoritative organisation in the world is the United Nations. And I think the average person can agree: the UN will give a platform to some fully fledged lunatics sometimes (check out the General Assembly just past).

Gavin Andresen could speak at the UN about XT for all I care; the fact that Gavin could arrange such a platform from which to speak does not actually make what he's talking about correct.
