At Zócalo, Mexico City’s central plaza, are (left) professor Jerry Coyne, author of Why Evolution Is True, Gerardo Romero Quijada, founder and activist with Mexican Atheists; and FFRF Co-President Annie Laurie Gaylor. (Their spread-out arms are in honor of Dan Barker, who does this trademark pose wherever he travels.) They were sightseeing after the conclusion of the second colloquium on Mexican atheism Nov. 2-3. Gaylor spoke at the conference, as did Coyne, Michael Shermer and several Mexican scientists and freethinking activists. The Governor’s Palace in the background features a major Diego Rivera mural which is strongly anticlerical and explicitly celebrates Mexico’s formal separation between state and church.
