Liberal Consensus Disorder

So, I was/am watching Fox news (I'm a liberal, but my Grandpa is a conservative and he turned on the TV. But he's sleeping) And they were talking about a racist comment/joke on MSNBC. They said that they suffer from "Liberal Consensus Disorder," where if everyone around you thinks like you and laughs at all of your jokes, you think that everyone will laugh at whatever jokes you make, and they do, but the rest of America is saying "You're a kind of a jerk." I saw that and I thought, "REALLY? FOX? ONLY LIBERALS DO THAT?" So, yeah.
