It was stated in so many words by socialist (though he risibly denies it) and Progressive-Democratic Party candidate for US Senator from Michigan, Abdul el-Sayed:

…if we took seriously the idea that all of our kids were all of our kids. If we started with that idea that every child is our child….

Too many people on the right are writing this off as just so much Kamala Harris-esque word salad, and that’s dangerously failing to hear what he’s saying, what Party and its Democratic Socialist of America members have in mind for our republic.

El-Sayed is clear here. Children don’t belong to the parents; they aren’t the responsibility of the parents. Children are the responsibility of the community, of the state. Children are the state’s property.
