The groups that make up the broader freethought community — atheists, who don’t believe in a god; agnostics, who are unsure; secular humanists, who seek to replace god-centered religion with a man-made ethical system; church-state separationists, who just want religion kept out of public life; and scientific skeptics, who work to overthrow superstition and pseudoscience — have two things in common. First, they oppose the hegemony of religious, including New Age, thinking in American culture. And second, they all have roots in very male subcultures.
