Why did the Bolsheviks mistrust the family upbringing of the child?

The bottom line was that parents, a family are not a state, and therefore there is always the possibility that something wrong will be put into the child’s head, something that the Bolshevik ideology does not imply. Therefore, they relied on the fact that the child will undergo socialization through state education. To this should be attributed the factor that not all parents could be loyal to the regime that was established in the country by the Bolsheviks, and therefore anti-communist sentiments could arise in the heads of children.
