Correlation, Causation
A large survey conducted by Esquire magazine, on “the state of the American male”, determined that liberals have 60% more sex than conservatives (3.9 hours a week versus 2.4), and that atheists and agnostics have 20% more sex partners than those who believe in God (10.7 versus 8.8).
Most people would likely assume that’s because agnostic liberals like myself have lower moral standards, and therefore more sex.
I, however, contend that causation runs the opposite direction: there’s nothing like dating / sleeping with a lot of women to shake your belief in God, or to cause you to support your right to marry men.
