The pros are that humans are allowed to make rules for the good of humanity vs the good of a god. The cons are that humans may lose sight of what is good for the whole vs what is pleasurable for the few. A close look at religious set-ups temps a secularist like me to think that religious leaders make rules that please them vs what is good for the people. The leaders mistake their own will for God’s. From that perspective, it all boils down to the same thing: Humans have since time immemorial been led by secularism except they were deluded to think there was a god at the helm represented by a holy man on earth. I realize statements like this tend to make enemies of the faithful but I challenge them to closely examine the charges and be sure that no such charges can apply to themselves personally.
