So Frankie Boyle is in trouble again, but this time I really think he hasn't got much of a defence...

or
Boyle has talked about his plans to quit stand up and, in my view, that is probably no bad thing.
Personally I don't think that the defence of "it's only jokes" or "comedians should be able to tackle any subject" rings true in the case of guys like Boyle. Yes, of course, comics should be able to talk and make jokes about any subject. However, let's not pretend that Frankie Boyle serves some higher purpose. Unlike other comics he doesn't make jokes about taboo subjects in order to highlight hypocrisy or make any kind of intellectual point...
The man just seems to like making nasty jokes about people based on the most ignorant of stereotypes. So while he must, of course, have the right to say such things, I personally don't see any reason he should be applauded, encouraged or defended for the manner in which he goes about it.
Frankie Boyle has always struck me as a massively bitter person, comedically hitting out as a coping mechanism. His comedy is of the playground - nasty, shallow and spiteful... and intellectually negligible. So personally I'll be glad to see the back of him (and any other comics who follow his, frankly cowardly, formula for success). His is not a massive talent - to be honest, any comedian worth his/her salt could come up with funny jokes about the physically or mentally disabled, paedophiles, rapists etc. Making these kind of jokes isn't a sign of bravery, quite the opposite in fact.
