The poor devil grabs at any loony thing that passes by and attempts to get it into the mainstream - he's been suckered by con-men all his life, I think. The whole family seems to have a touching faith in homeopathy, for example, and he wants to be not 'Defender of the Faith', but 'Defender of Faiths' - as though such a thing were possible, and didn't leave those of no faith (half the population roughly) without his magic 'defence'...

I think it's sad.
