Proud Atheists could always be counted on to provide a thought-provoking and often funny take on religion. Most of all, I came to associate Mark's work with the sort of passionate atheism I love to see. He routinely delivered sharp criticism of religion that I can only compare to a kick in the nuts. He was not about pulling punches, and in this way, provided a great model for what some choose to mistake as "militant atheism."
Mark, you have an open invitation to write guest posts here any time you want.
