I once made an atheist’s head explode by noting his stance was simply another form of faith. Believers have faith there is a God, Allah to Zeus, take your pick. Atheists have faith there isn’t. Neither stance can be demonstrated with actual evidence.
But like all forms of faith atheism is just as susceptible to the human impulses to find excuses for being dicks to other human beings. Which also demonstrates my first point that atheism is just another form of faith.
