Many would say that Marine Corps doctrine (or military doctrine as a whole) is demonic. Especially with what you have just said, that just seems to add to that statement. This is even coming from non-pacifists in the military. I've talked to a number of people who have admitted that the military is not a good place for Christians and the stuff we do can be satanic.
And for the (number) of people you have talked to...I can easily say the same thing about my stance....people who have studied 20, 30, 40, 50 years intently......so....Your points are moot!
