Bolsheviks were absolutely pushing quite radical ideas on sex, rekationships and family in the early 20s e.g. Kollontai with her Glass of water theory.
> 1918 Code on Marriage, the Family and Guardianship
> One year after the Bolsheviks took power, they ratified the 1918 Code on Marriage, the Family and Guardianship. The revolutionary jurists, led by Alexander Goikhbarg, adhered to the revolutionary principals of Marx, Engels, and Lenin when drafting the codes. Goikhbarg considered the nuclear family unit to be a necessary but transitive social arrangement that would quickly be phased out by the growing communal resources of the state and would eventually "wither away". The jurists intended for the code to provide a temporary legal framework to maintain protections for women and children until a system of total communal support could be established.
Not really, just the notion that trying to abolish family is somehow the hallmark of totalitarianism doesn’t seem like sound reasoning, and indeed it isn’t confirmed by historical examples.
They did stuff like legalizing divorce, or collectivization of parenting.
