Fry and his ilk are not interested in the blasphemy laws, their overriding intention is to bring down the Church, which they see as the last bastion of social conservatism. They are outraged that the Church still refuses to accept homosexual "marriage", that is what drives Fry and most woolly headed "liberals" who seem to admire him.
If he were only an idiot like Joe says there may have been an excuse, but he is much worse. A menace to society who would deprive decent people of their faith.

I notice the Mudcat "liberals" confine their faith bashing to the Christian faith.
