Theres 2 or 3 of them on a forum I go to, they've had multiple dozen page threads where they repeatedly fail to grasp the concept of relativity and lack of absolute measurement. They dont however bother me too much, because they are not very rich and powerful, are not as far as I know trying to get into schools, and generally are unlikely to go and burn down a physics lab. (Mind you, hate mail is bad enough)
I like the dismantling of the accusation that Einstein fudges his figures for Mercurys perhelion.
I sometimes think that what we need is a cranks research university, with a grant attached, so that the cranks can argue amongst each other about what experiments can be done to prove their theory is correct. That is certainly one of the similarities between them and ID'ers, that all they have to do is prove the old theory wrong, hardly ever do they have anything better to replace it with.
