Edits, ahh you confuse the western family as being just a non extended family.

The criticism is against all families, extended or not. The idea from Marxism is that tribalism starts in the family unit. The aim is to get the village to raise the child, not just allow the grandmother to lend a hand.

The western family includes the European models, it doesn't only contain the Protestant isolated family structure.

Your question should therefore be re written as "why does advocating for having a family to be made up of people not related to the child be seen as problematic"?
