I actually came across a truther at work today, which was a real surprise. The conversation was civil, and he did show some familiarity with anti-truther arguments. A couple of my points seemed to register. I said that planting weapons of mass destruction would require complicity from a far smaller number of people than what he was proposing.
My question is, what’s the best source for debunking the common truther arguments? Is there anything better than this Popular Mechanics article?
