Oh my god.

[Smaug]

I don't care if people say it and I use this phrase myself now and then. The initial connection to religion is so eroded that it doesn't matter much anymore. I also generally don't care if a person is a Christian or a Muslim or whatever unless they take their faith too far and too seriously. I've met people who were not religious but very superstitious and it's as irritating as dealing with an overzealous religious person. It is generally very irritating when someone pushes their irrational beliefs when dealing with serious matters.
