What binds many atheists together is an unshakable conviction that they know everything there is to know about religion, namely that it is irrational bondage to immutable doctrine. No amount of counterevidence can convince such atheists otherwise. What irony! But where do they come by this knowledge about religion? Their expertise seems to be derived by virtue of sheer sentience alone.
By contrast, if a theologian were to broadcast her convictions about molecular or evolutionary biology without some years of careful reading and study, she would be met with jeering laughter and summarily dismissed. Why then are uninformed atheists who have never read in theology exempt from similar derision? Sadly, every pedant believes himself entitled to his unearned convictions about religion.
