So I though it was sexist drivel from the part here, but I went and looked at the bottom and found this gem of a quote:

"The workers’ state needs new relations between the sexes, just as the narrow and exclusive affection of the mother for her own children must expand until it extends to all the children of the great, proletarian family, the indissoluble marriage based on the servitude of women is replaced by a free union of two equal members of the workers’ state who are united by love and mutual respect. In place of the individual and egoistic family, a great universal family of workers will develop, in which all the workers, men and women, will above all be comrades. This is what relations between men and women, in the communist society will be like. These new relations will ensure for humanity all the joys of a love unknown in the commercial society of a love that is free and based on the true social equality of the partners."

So I don't think it is nostalgic about the past, but rather expressing that those old systems shouldn't be clung too. Idk, insomnia has rendered me bleary so I'm saving to return later.
