The difference between Clarkson and Brand is that Jeremy Clarkson has a brain. Don't forget the tasteless and tedious Brand wrote a book and called it "My Bookywooky". The brain of a comatose snail obviously.
So this furore about remarks Jeremy Clarkson made about lorry drivers killing postitutes is just puritanical bandwagon jumping.
The big difference is that Clarkson didn't phone a murder victims family gloating. So get off his back.
