The worst part about Family Guy isn’t the most offensive jokes like this, it is that they are an obnoxious talking piece for the left. That is why South Park is the best cartoon to get political satire from, they bash both sides.
Back to the offensive jokes, it isn’t just Palin and Schiavo folks. Those instances just shined the spotlight on Family Guy, what about all the blatantly racist and anti-semitic jokes? I think Jews should be as offended as any other group by the jokes that comes out of Family Guy.
Personally, I think that is its biggest weakness. Its even-handed hatred doesn't make its fairer at all. Ultimately it's a show that anti-everything. Its anti-God, its anti-Human, its anti-caring. It's a show that fair because it drags everybody down. If you care strongly about anything, you are fair game for "South Park". The shows whole take is that anyone who cares is a fool, a dupe, a control freak and/or an interfering busybody. I once saw an interview with the creators where it was put to them that a particularly unpleasant episode might adversely affect children, to which the defensive reply came "frankly, we don't give a sh*t". Well, frankly, Messers Park and Stone, I DO give a sh*t. South Park may be surreal, and it certainly can be funny, but ultimately its more a cause for the decline of civilisation than Islamist terrorists or tyrranical politicians, because people can recognise the dangers they present.
