It can't be called incompetence if he makes the arguments he has been paid (and likely will again be paid) to make. The world is full of highly competent people who do exactly that, many of them lawyers. They're not called 'advocates' for nothing.

Perhaps instead of using the mindless daily news formula of pitting two self-interested views against each other to see who has better soundbites we should try to put rational, thoughtful people on the stage.
