When...did it become irrational to dislike religion, any religion, even to dislike it vehemently? When did reason get redescribed as unreason? When were the fairy stories of the superstitious placed above criticism, beyond satire? A religion was not a race. It was an idea, and ideas stood (or fell) because they were strong enough (or too weak) to withstand criticism, not because they were shielded from it. Strong ideas welcomed dissent.
