Using derogatory words like "teabaggers"

Ann Althouse posted a video of her husband Meade cleaning up after protestors who used a Communist slogan to deface a Civil War Monument in Madison, Wisconsin. It features a discussion of the term "teabaggers," which led me to the urban dictionary to find out the meaning of the term, which is now being used synonymously with "teapartiers." Althouse and Meade engage two protesters, a lawyer and a teacher, in discussion of the use of derogatory words.
