Taking with some atheist, you would think the best way to reduce religiosity is through score and browbeating.
Government vs. God? People are less religious when government is bigger, research says
Well we all know what happens there....
The trick is to have more atheists with less government.
I'm no real fan of government, but the lesson, if I understand it right is that society might need to do a better job. Ether by providing social services and having a situation where that they are not needed.
