Why are Democrats and Ron Paul supporters so angry?

One thing that I'd like to know is why are Democrats and Ron Paul supporters always so angry? To the Ron Paul supporters, you lost the nomination. Get over it already. And to the Democrats and Ron Paul supporters, get rid of the "9/11 was an inside job" people from your parties and campaigns. And also Democrats, get rid of Howard "Horse's Ass" Dean as your chairman. He's making you look worse than you already do.
