Religion Because Thinking is Hard

This meme conveys a common atheist attitude: that theists are stupid.  I think this is unfair.  Religion has occupied some of the finest minds history has ever produced, all who have tried to make sense of what is frankly a difficult world view.

Religion suffers from premise and approach issues - the premise is that the answers have been supplied (in the form of Sacred texts), and the approach is that these revelations need to be accepted on faith.

We atheists can disagree fundamentally about these issues, but to accuse theists of intellectual inadequacy is just silly name calling.
