What I can't stand though is people who go to see him, laugh at his mocking of group A, B and C but then get all self-righteous when he mocks their special interest group.
This, this annoys me more than anything Frankie Boyle comes out with.
I refuse to jump on the bandwagon to go see what he's said now, because that is exactly the reason he's saying it.
Its business. He, and whoever he is hired by, know that people will be offended, they know you will tune in to see it, they know that you will come onto websites like this to express your anger, lots more people will wonder what he's said and look, and then tune in next time to see if he says anything else worthy of a debate/rant, and so it continues - You are giving him free advertising.
His jokes may be offensive, but he is acting within the law, so at present the best thing you can do is ignore him. That's the only way he will go away really, if everyone stops playing in to the system I outlined above.
