Did "Family Guy" go to far with last sundays episode.?

are people too sensitive or did the show really go to far by poking fun at Sarah Palin. as a mom and a former health care worker I thought it was in poor taste but I considered the source. The show has made several jokes in regards to Jon Benet Ramsey and one of the characters (Mr. Herbert) is a pedophile and people seem to think that's funny(I see no humor in pedophilia) but the show targets everyone .Marlie Matlin thought it was funny when they lampooned her. Has this show gone to far or should people develop thicker skin . You don have to watch the show if you don't agree with it but when do you say enough is enough. I am curious about how others feel
