Are we better off knowing the earth is not flat? Yes. Are we better off without slavery which is not condemned by holy books but sanctioned it? Yes.
The only argument one can make is that emotionally some humans cant stand the thought that they are not the center of the universe, and that by believing it keeps them from going nuts. But that is not "better off" as far as knowledge. It is "better off" for the rest of humanity not to take the baby rattle from the brat who refuses to grow up.
So it is not either or, but it depends. We cant live in fear of change, and challenge to religion has always been where progress has been made.
