Teaching children that God created universe in 6 days, and that Earth 6000 years old is child abuse. But I digress.
Actually the latest science says that a religious upbringing improves children's health into adulthood.
Religious upbringing may be protective factor for health, well-being in early adulthood

Belonging to a social club, meditating and exercising all have the same effect, without a boogie man or Santa Claus. Not sure what your point is.
I would not hire anyone who believes that Earth is 6000 years old, or believes that the religious scriptures are the "word of God", no matter how happy and social they are.
People who believe those things lack critical thinking skills and have poor judgement.
You can't do anything without God - not even belong to a social club - because He penetrates everything if only for the purpose of holding it all in existence. Go to the Scientific proof that God exists? thread - https://bitcointalksearch.org/topic/scientific-proof-that-god-exists-737322 - to see that God exists, and how He controls everything.
People who do not understand that the Earth in its present, general physics form is only about 6,000 years old, might have skills that make them worth hiring, even if they have a different religion than you.
