For the first time in history, the U.S. military hosted an event expressly for soldiers and others who don't believe in God, with a gathering sort of like a county fair Saturday on the main parade ground at one of the world's largest Army bases.

In high dudgeon over a tweet about transgenderism from prominent atheist and evolutionary biologist Richard Dawkins, AHA excommunicated Dawkins for heresy, finding his browbeating confession insufficient. On Wednesday, however, the prominent atheist and psychologist Stephen Pinker came to Dawkins’ defense, citing the bedrock principles of Humanism in an act of defiance against the Humanist church.
