In late July 2010, Bad Astronomer and skeptic, Phil Plait, gave a thoughtful public presentation called "Don't Be A Dick." This presentation discusses how one presents their skepticism to the public and how they discuss it publicly. There was a lot of positive reaction to the talk, but also some criticism.
I agree with Phil, partially because this is the method I use to engage with those who believe in some form of magic, and also because I agree with the arguments he uses to support his position. What are your thoughts?
