I have to ignore all the guys I work with. I do construction (Line work) and work with people from all over the country. I've got about 3 guys that view the world about the same as me, they're the only ones I talk about that stuff too.
I'm polite to everyone else and just mind my own business, sometimes I'll make fun of how stupid they are with a joke or something but they rarely take offense. I can't go on to much about it, the owner of the company is a very religious man. He'd flip if he knew he had an atheist running jobs, pretty irrational guy... like most Christians.
