Why would a church want to advance an atheistic philosophy?

During the Viet Nam War, many seminarys accepted any man who was interested, because the government still gave student deferments for going to divinity schools after 1968. They accepted any warm male body, even when that body held such minor opinions as not believing in God or believe church dogma or things like that. Many of these people went into the ministry, because they liked it, not because they had an actual calling, unless you counted being a Marxist a calling.

That is one reason why there are so many marxists in the denominations which opposed the Viet Nam War.

Well, your response has nothing to do with the original conspiracy theory. Which was that that laundry list of churches formed with the express purpose of advancing Marxism.

You're proposing another tinfoil theory, which is that legions of Marxists joined churches to avoid military service, thus explaining the opposition of several churches to the Viet Nam War.

I find the simplest explanation is often the best. Most likely these churches opposed the war, since they believed it to be immoral. Any draft dodgers would be junior clergy members at best during this time...they would certainly not have the pull to influence the senior policy making decisions.
