I can't believe you pulled a "both sides" line comparing The Daily Show and The Rush Limbaugh Show. This is not apples to apples.
Perhaps Rush's (or to use a more current example, Tucker Carlson's) viewers are so twisted that they no longer recognize what a comedy show is. That doesn't mean we become just as unreasonable as they are. It's not The Onion's fault when someone "eats the onion".
