This was one of the first things that went through my mind - the hate that gets spewed at anyone on the Right is absolutely vicious, and this is by the same people who criticize us on the Right for being hateful.
I have listened to Rush for years. I'm new to Hannity but have listened to him a few years ago and catch him every so often, now. In either case, their criticism of the Left is mostly satirical and even comical, sometimes frank and in the manner one would chide an adult who has done something bad (ie, Rush's calling the Dems "sick" for their politicizing of the Arizona shooting), but never have I ever heard mocking of someone's misfortune or fantasies about killing this liberal or that. Contrast that with how the Dems react when you mention Bush or Cheney or Palin, or perhaps Rush's prescription drug incident or Sarah's daughter's pregnancy - then you see what is real, genuine, palpable hatred.
We know this, but of course the Dems don't get it. They think that because a liberal says X, X must be acceptable.
