On the internet someone who posts inflammatory, extraneous, or off-topic messages in an online community, such as an online discussion forum, chat room, or blog, with the primary intent of provoking readers into an emotional response or of otherwise disrupting normal on-topic discussion is called a "Troll". In American politics, they are called the Tea Party.
A lot of the Republicans in congress (E.G. John McCain's hobbit comment.) are sorry for allowing that group of intolerant, misinformed, ridiculous sounding, ranting, angry at the wrong people, weird crack pots. Ask one of them why they are walking down the middle of the street, carrying a sign, and yelling, "Bring back our freedom", as if they don't realize if they actually were in a dictatorship or communist country that the government would send troops out in the street to disperse, shoot them, or arrest them. They are told to be afraid of Czars because they are a Russian word. That started along time ago and became popular to discuss during the Reagan era, using the title that Reagan gave them at the time, with his appointment of a Drug Czar. It was just another way of calling them "the guy in charge" using a term that past presidents, including Reagan, thought was somehow appropriate at the time. These people actually have been told and believe that these Czars are here from Russia infiltrating our government. Czars have no executive power although these people can't understand something simple. Trying to convince these simple minded fear driven Trolls about that is a task in itself. They think Glen Beck, the master of Right Wing Ranting over nothing using fallacy logic is a logical thinker. That is just sad. What is the nation coming to?
