I'm not religious but I know a lot of religious people from all sorts of religions, they take advice from non religious people all the time, it not like they ask you first, it's like an atheist not taking advice from a religious person, it would be stupid. in U.K. (Where I live anyway) religion is a very personal thing, people normally keep it to themselves.
theres a jehovah witness place down the road from me, Americans mainly, always found them to be pretty smart and likeable actually but that's just me..
