Or they may be Muslims. Or they may be pagans. Or ....<quoted text>They may not fall into either group. They may believe in a god but aren't Christians. They may be agnostic. They may be undecided. But I don't see how lying about actually being a Christian puts them in our group. Plus many prisons ask prisoners to identify themselves by religion specifically to classify people becausee of priveledges for particular groups. You find me a prisoner who won't say he is a Christian to get out of his cell for extra visits and church and to gain points from people who will dictate their fate within the criminal justice system and I'll show you a prisoner who has never spent a day behind bars, doesn't know a person who has, hasn't talked to someone who has, and doesn't know how to scam a system. Personally I'd be interested in meeting such a person cause as of now I am skeptical such a prisoner exists!
You play the no true Scotsman fantasy like it's an bludgeoning weapon. Point is, your religion does not stop it's members from breaking the law, which is logical since your religion commands people to break the law.
