But there’s no question that the Soviet Union looked down on the traditional family.
Oh sure, but that’s because they wanted to raise the next generation to think of the state as its family and the authority in all matters. In addition to denigrating the family, the first couple generations of Communists also suppressed the Orthodox Church, but with only some success. It’s coming back, and Putin supports it.
In the US, Leftist ideology is still a mishmash of old Communist class rhetoric (which includes family suppression), but there are some new factors: there’s no need to actively suppress the Church—pederasty has so infected the Church that it has destroyed its own brand. Self-hating anti-patriotism is in vogue... even in the USSR, they fought for Mother Russia. Sexual deviancy has been promoted more than ever before (there may have always been gays, but the hormonal and surgical techniques necessary for transgenderism are more recent, as is its promotion). And, instead of a government-controlled press, we have a Deep-State-worshipping press, which if you include Hollywood and Netflix and Amazon, is far more powerful than Pravda or Izvestia.
History doesn’t repeat, but it rhymes. The key idea, both in revolutionary Russia, and for the leftists here, is to destroy any sense of order, to create chaos, because they hope they will be able to pick up the pieces and emerge as the leading faction.
