Apparently sarcasm and satire are too indirect and subtle to be understood by those who live in a strict black vs. white, good vs. evil, dichotomous world. Research has now shown, "[...] individual-level political ideology significantly predicted perceptions of Colbert's political ideology. Additionally, there was no significant difference between the groups in thinking Colbert was funny, but conservatives were more likely to report that Colbert only pretends to be joking and genuinely meant what he said while liberals were more likely to report that Colbert used satire and was not serious when offering political statements."
In other words, conservatives don't get the joke.
