In almost all cases, your religious preference would be respected, and no one would give a shit. Unless of course you actually did mention the Flying Spaghetti Monster, because this would be an obvious attempt to demean another person's religious beliefs.
Yes, Christians are in the majority in the military, but they are also required by regulation and therefore law to treat everyone with respect. There are Muslims, Jews, Scientologists, Wiccans, Satanists, Atheists, Mormons, Mennonites, Taoists, Bhuddists, Harri Krishnas, Jedis, and many more in the United States military. I've even had a friend who claimed to observe traditional Norse beliefs.
Every official event that I've been to has had some sort of Christian benediction, which is technically unethical, but at the same time, if it brings comfort to the overwhelming majority of my friends who may soon be risking their lives in combat, isn't it more damaging to attempt to deprive them of it?

Do you hear the hypocrisy, the conceit? Who gets to decide which fairy tales are blasphemous? Whose moral outrage is justified when others dare to disagree with their religious beliefs?
