Here's my take on it. Family Guy is a sillier version of South Park. It does what South Park does with the satire and the humour, but is more...I dunno, blunt I would say.
I don't know if you saw the latest Family Guy episode where Brian becomes a follower of Rush Limbaugh and decides he's going to become a hardcore conservative, but the entire episode takes a stab at the right wing extremism present in contemporary U.S. politics. There's nothing subtle about it. Every time Brian or Rush say something, the message is obvious: U.S. Republicans are f**ked up. South Park would be more tactful in its approach and be more intelligent about it certainly but FG isn't trying to be something it's not. It is what it is.
