Currently the term "Truther" refers to someone who adheres to the beliefs espoused by the 9/11 Truth movement. Truthers are conspiracy theorists that, like all conspiracy theorists, blatantly distort facts and quotes. These are the Bible thumpers of 9/11.

Some of them believe that the government orchestrated it in some complex, cockamamie scheme; others believe that the government simply let it happen.
Debating a Truther is like banging your head against a brick wall - painful and futile. You are likely to be called many things by them: ignorant, stupid, sheltered, blind, scared of the truth, a sheep, a lemming.
