The truth about many Eastern Bloc dictatorships is that they were aggressively socially liberal in terms of their assault on the family structure and on religion. Stalin was a deviation rather than the rule, and even with him, I'm not sure if his praise of the nuclear family wasn't more wrapped up in his cult of personality with him as the "father figure". Stalin had attacked religion consistently up until 1941 when he figured out that it was helpful in both shoring up his own position in regards to the cult of personality, as well as in the war against the Germans, much like the Tsar had used religion in 1812 against Napoleon.
The entire living model of massive tenement housing and planned economic activity was supposed to dissemble intermediary institutions between the state and the individual, such as the family and local community organizations not tied to the state (like independent trade unions, churches, clubs, etc.)
And religion was relentlessly attacked in this period in some Eastern Bloc states , while others merely tried to co-opt churches into state organs while dismantling any semblance of their original doctrine.
I suppose a good example however could be the Turkish military when it resorted to authoritarian coups in the name of secularism.
