I don't think that fundamentalism has anything to do with Jesus Christ. They call themselves Christians but if that's Christian count me out. Fundamentalism is built on fear and greed. They're telling you to give them your money otherwise you're going to hell.
All I try to do is create an atmosphere that seems comfortable enough that it removes tension and everyone feels free. If they feel free then behaviour happens small moments happen and that's what ultimately works the best for me.
