They do regularly wanna drug, carve up, and sterilize children.
They want parents barred from having any say regarding schooling, literally to the point of having the father of a rape victim arrested.
BLM has a stated goal of demolishing the nuclear family.
The thing is, this focus on collectivizing kids isn't a new thing. We also know why ideologues do it, and why it fails.
The Kibbutz runs itself in this way regarding kids -- namely, your kids aren't yours, they belong to the community.
The difference is that the Kibbutz does allow people to leave voluntarily. What we've seen is that most people do leave when they have kids. This shouldn't be a surprise to anyone. I don't have kids; but, I would take a bullet for my niece or my nephews in a heartbeat.
Really, the only reason why the Kibbutz still exists is that Israel subsides it.
What the illiberal Left is trying to do here is implement what the Kibbutz has been doing for more than a century, but actually have it enacted by government institutions.
This is gonna collapse on itself. It's just a matter of when.
When your strategy for perpetuating your cause is the mutilation and indoctrination of children, eventually the parents are gonna draw their guns and shoot your paedophile asses.
