Outside a small circle of Americans, Fox News, and far right whack jobs, no one really takes the Tea Party Movement seriously. And, honestly, how can you? Glenn Beck, Michelle Bachmann, and Sarah Palin, their de facto leaders have proven themselves to be a couple sandwiches short of a picnic. They claim to be Christian while displaying utter contempt for their fellow human who does not believe as they do.
And the name these conservatives chose for themselves? Well, now that they know it's other definition, Teabaggers don't like the label they have been given. By themselves. No body gave it to them, they chose it for themselves, and now, they don't like to be called it.
I can understand them not using the Urban Dictionary, after all, these people are suburbanites. And urban connotes something more akin to President Obama than they care to be at any given time. How out of the loop did they have to had been to not know what popular usage of the phrase meant? I'm sure they think that a hot karl has something to do with Karl Rove.
Conservatives like to play the victim when they're not in charge. But in this case, they're victims of nothing but their own ignorance.
