Depends on your definition of "Christian right wing". Technically back in WWII the so called "allies" were made up of commies + "Christian right wing", were they not? Therefore back in those days Western right wing Christians were quite good buddies with the communists. They were even such a love birds to share nuke technology later on (whether with or without consent matters not, as in other love stories), which in turn lead us to the endless problems with Russia's imperialism up til this day. Therefore it's no surprise they ended up sharing their attitude to porn too.
Okay, few things:
1. I don't think it's historically fair to clump all the allies as either communists, or the "christian right wiing". That leaves out plenty of nuance, or are you claiming that Churchill and the British are either one of the two? Or the Chinese? Or the French?
I feel like Evangelist christians as a political actor and/or movement is pretty fundamentally an american thing. Elsewhere in the world such movements exist obviously, but they're not nearly as politically minded, or large, as in america. And while American politics in the 1930s and 40's are not something that I'm necessarily knowledgeable of, if memory serves, there was no "christian right wing" party in the americas at that time.
2. Historically almost none of the allies were very good buddies with communists. I mean, Stalin tried to warn the western powers (at that point Britain and France) about Hitler and his war aims in the 1930s, but neither really listened, partly because they underestimated Hitler, and partly because they did not want to ally with Communists. Remember that all of these powers intervened in the russian civil war against communists, or supported anti-communist factions.
3. if I'm not completely mistaken, the nuclear secrets were gained from America by espionage, i.e. Spying, rather than americans freely giving the secrets away to Moscow because they were "such good buddies" You try to claim that it doesn't matter weather they were leaked by spies or freely given, as if those two are remotely the same thing. Especially when your further claim states that this is an assumed act of friendship between the two.
In fact, you essentially destroy your own claim here. At the same time you claim that communists and the rest of the allies were such good friends that they shared the secrets of the atom, but also you aknowledge the cold war. So which one is it? Were they such good friends that they shared state secrets, or such good friends that the releationship broke down immediately after a common enemy was defeated?
4. What exactly does this have anything to do with porn?
Additionally, while it's true that pornography (and possibly sex work too) were banned in Soviet union, do not assume that the soviet union is some grand leftist dream. It's a dream to lunatic tankies. That place was an authotarian hell hole, by the end.
If you were to study modern socialist or anarchist thought, they're most often than not proclaiming sexual liberation, legalized sex work, and as much pornography and masturbation as you are want to indulge in.
It's not the left wing that wants to ban or limit pornography and sex work, bud. You're barking at the wrong tree.
