Trying to avoid the things that will cause this to end badly.
In a world that is becoming overly sensitive to the opinions of others (political-correctness-gone-mad) we are forgetting that every society needs an outlet for a differing opinion.
All cultures seek this outlet in various forms. In America it is Saturday Night Live, the National Lampoon, Mad Magazine, the Airplane movies...and, with irony to Mano's signature, guys like Will Rogers. It's called satire.
Top Gear, in large measure is a satire of other car-fan programs like Motorweek Illustrated. It satirizes those serious (and often made-of-oatmeal) presenters. May, Hammond, and Clarkson also target, through their own self-assured bumbling, the bailing-wire-and-duct-tape DIY'ers that always make a mess of 'custom work'. Just like - well - me. I'm not offended by that.
We don't know that anybody punched anybody at TopGear. But trying to harness a satirist like Clarkson is the same as gutting the program. It is not a live program. It is produced. If the BBC's producers don't like the content they can cut it or alter it. BBC elects to censure whole episodes? Stupid. We should all just move on.
