Over 100 years ago, Russia became core of USSR and the pioneer of international struggle for workers' liberation, poverty lifting, enlightenment, scientific progress and propagation of socialism and communism.
Now -- in my humble and maybe biased by liberal propaganda view -- Russia is one of the most reactionary, conservative, backward-looking, clerical country. Please excuse me posting some liberal, imperialist shit here, but seems that Kremlin officially admits going far-right: https://www.wilsoncenter.org/blog-post/kremlin-finally-puts-together-ideology
Speaking locally, there seems to be evidence that Polish far-right party PiS (Law and Justice) is backed by Kremlin as well as the extremely influential priest, Tadeusz Rydzyk, founder and director of the ultra-catholic, conservative Radio Maryja station has/had ties with Polish and Russian security services before the end of People's Republic of Poland and USSR (sic!). I have some generally available videos, but in Polish, sadly.
Could you tell me how far this is true? If so, what purpose had the late communist states and today's Russia in spreading far-right propaganda? WTF went wrong?
I'm not aware how true this is for Russia, but Orthodox Christianity has been entrenched in Russia for centuries. 70 years of communism was not enough to dislodge it. This plays a major role in the way the political winds are blowing to the right, not just in Russia, but all across Eastern Europe. Orthodox Christian churches are very prone to fascist rhetoric and extremely conservative. From the medieval ages, Orthodox churches have managed to weave themselves together with national/cultural identity in their areas, to such a degree, that they are considered one and the same nowadays. In most Eastern European countries, you will find Orthodox high-ranking priests behind far right parties, conservative movements and racist/anti-immigrant actions.
There's a lot of diffusion of ideology happenning across all Orthodox churches, so I assume this due to what's going on where I leave.
Orthodoxy is also very prone to conspiracy theories, especially those coming from the right in the West. Such as Harry Potter is a real witch handbook, Pokemon are evil, hollow earth and lizardpeople conspiracies, etc. Anything that reinforces the belief that the devil is alive and actively seeking to control the world.
Catholicism had exact same role in the catholic socialist countries. Both churches served as capitalist 5th column in each and every socialist state, restitution of capitalism was in their interest.
