I am an atheist/agnostic, I still pray lol (for pretend) out of respect for others. Not that big of a deal, true or not, I worked with homeless people before an yes they are required to follow rules (at least curfew that I know of) if they stay in one of the church shelters. I don't see why any atheist would have a problem with praying in this manner unless they have some sort of stick up their ass, I don't understand the harm in being respectful of others beliefs especially if they are feeding and sheltering you no matter if they are retarded. Just like if you are living under your mums roof, you should give her respect, it is called manners, dignity, morals, and being an adult.
