It’s unlikely you’ve ever been angry at unicorns either. We can become incensed by objects and creatures both animate and inanimate. We can even, in a limited sense, be bothered by the fanciful characters in books and dreams. But creatures like unicorns that don’t exist—that we truly believe not to exist—tend not to raise our ire. We certainly don’t blame the one-horned creatures for our problems.
The one social group that takes exception to this rule is atheists. They claim to believe that God does not exist and yet, according to empirical studies, tend to be the people most angry at him.
