Or perhaps The Onion takes shots at everyone and people are just more likely to notice the stuff that offends them? Drew Carrey told a story about how he got hate mail from people after his sitcom had a punch line involving Polish people. He also received a lot of angry letters about a joke involving mental health. The first group was very offended about the Polish joke and was incredulous that his show was allowed on the air. The second group was also highly offended and similarly baffled by his success. The interesting part is that the first group never complained about off-color jokes about mental health, and the second didn't seem to notice the Polish jokes. Each group only noticed the stuff that touched on their personal biases and ignored the rest.
