I can't disagree with that. Instead of Jesus Christ, people actually pray to the god of the greenback. The "Christian" part is just there for show.
Self-professed Christians included. In fact, the ones who advertise their Christianity most openly are usually the ones you have to me most careful about.
Sometimes.. i think people who want to control the behavior of others through lawmaking are the ones to be careful of regardless of their creed. Especially those pushing scientific theory as a gospel that you must live by if you want to be a good person and not be belittled as a denier.
