The party out of office is always angrier. You can find polls from 2008 (and probably 2002, 2004, and 2006) showing that Democrats were angrier.
Hey, I feel kinda angry today. How about you? You feel angry? Let's go join the KKK and blow up Charlie Hebdo and the World Trade Center and Gabby Giffords..... wait, what? Already been done? What do you mean by that? Someone beat us to the punch? Who's stealing our righteous thunder out there? Say it ain't so, Joe, say it ain't so.
One starts to get the idea that accusations of that kind are really being used to control one, while competitive others go crazy and do their vile thing without check or rebuke. Notice that Bill Ayers has never taken the weight of his cop-killing, nor his gun moll hers. But we're "Rethugs".
