“It is wrong always, everywhere, and for anyone, to believe
anything upon insufficient evidence.” — William Clifford
If you can believe without evidence that men are born evil and deservedly condemned to eternal torture, and that Jesus was crucified as a blood sacrifice to a barbaric Bronze Age god in order to expiate that innate guilt, then you can just as easily believe that Mohamed galloped off to Paradise on a white horse and expects believers to kill those who doubt his teachings. The content of those beliefs is different, but their sanction is identical: Faith, belief without evidence, belief in spite of evidence.
Domestically and internationally, faith is the moral evil that must be confronted and defeated.
