Why do people complain about "offensive" material on Simpsons or Family Guy? That is (partially) what those shows are about. Over the years they've been offensive to Mormons, Unitarians, Hispanics, Texans, Single Dads, Republicans and probably every other niche group in the planet.
I've watched Simpsons since it was a short on Tracey Ullman, and they have once offended me enough that I turned it off. In fact, I turned the TV off for the night and went in the other room. In syndication to this day that episode makes me emotionally tighten up. I never filed a single complaint, wrote a single letter or missed an episode out of spite. If you watch that kind of series, you sign up for your ox getting gored occasionally.
