Fuckin losers just tryna tell other people how to process the existential ennui of this meaningless existence. If you find that with some new-age pagan shit than comrade its all good, when we cut off bezos's head i'll help you make a pentagram out of the blood or something idk what you do.
Orthodox marxist states (USSR, CCP) had state atheism, but marxist theory is ultimately a material theory. It does not include the spiritual, which can either be interpreted to mean that there is no permissible spirituality within the marxist worldview, or that nearly any spirituality is compatible so long as it follows the material beliefs of marxism. This can be seen in South America with liberation theology.
Christian socialism has been around forever, even older than the USSR.
