Don't forget people, this was 1950s America...
Everything then was about God and country. Conform, obey, anything else is bad and dangerous. All these flicks were heavily overseen by government censors. Even a power that could dare question, and defeat, America would still suffer the wrath of God for doing so, because if God is for us who could be against us. At least that's the parochial thinking of the time. And even Hollywood had to kowtow to that. So, whilst it may be offensive to us educated and modern people just take it with a massive grain of salt as it were.
Even though we have a long way to go, look how far we've come from the tyranny of religion in just a few short decades. A couple of centuries from now and the evil superstition of religion may be purged from our race entirely - if we survive. Then again, over half the people you meet are of below average intelligence, and so long as there are stupid and weak people, we'll have religion.
