There's something about truthers that makes me want to put them all in a big field and tell them off in a very strict voice.
I don't feel at all the same way about any other conspiracy theories; Apollo, JFK, bin Laden's death, birthers, Diana's death, Prince Harry's parentage, chem trails. It seems that most events have a conspiracy theory attached, but 9/11 twoofers truthers really make me seethe.
