Atheists have begun "de-baptizing" themselves. Sometimes this involves buying a certificate that they can hang on the wall; sometimes it involves having a guy in robes point a blow-dryer at you to dry off any remnant of the water.
One wonders why atheists, having abandoned religion, still need its customs and ceremonies, even if only in the form of mockery. Oh no -- one doesn't wonder, does one? One knows.
Anyway, it might be an angle to approach the followers of Jesus in John 6 who just can't hack it, and turn away. (After five slow weeks of John 6, we suspect that many of the faithful will be a bit squirmy in the pews themselves).
