He is a TV personality. How he acts on Top Gear could be radically different to who he is (I doubt this too). The facts is, the series sells and people watch it. Who doesn't hate the TV licence? But what can we do about it?
We can stop paying the licence or protest it for a start. And I don't think his TV persona is any different from the person he actually is. He's just not a PC person, but you kinda have to be nowadays if you want to work for the BBC.
