So what you describe when you say, "The creeping, insidious assumption that our children don't belong to their parents, but that they belong to the nation" it is already happening, except you have to substitute "the community" for "the nation."
So because the cult does it, the government can do it? That makes it okay?
No. The courts are extending their powers far beyond the limits they should be allowed. Nobody cares right now because it’s just a bunch of whack-job cultists, but have you ever known the government to relinquish power?
