Why would government schools not teach about limited government? Do you see the conflict of interest? Non-Government Organizations (NGOs): A recent trend, these federal-grant-powered "non-profit" corporations contract their "services", a.k.a., agendas to local and state governments. These tend to be environmental organizations, pushing for farm plans, water rights regulation, land use controls, LEED bulding ordinances, and just about any other illiberal control freak regulation you can think of. Such a deal: our taxes pay NGOs to instruct our government on how to oppress us. Now, mind you, I might personally want a LEED home or office building. Storm water runoff might be a problem here and there, and I'm not opposed to using permeable paving stones in lieu of poured concrete where it makes sense. But why do these people want to use the force of government to compel the rest of us to join their religion? If their religion is so great, wouldn't we join them voluntarily, if only we knew "the truth"? Everything we need is already right there in The First Amendment. Local Government: Lacking adequate formal education about constitutional principles (see above), local governments (city councils, county councils, planning councils, etc.,) take an oath of office to uphold and defend something they know scarcely about. As such, they are all too willing to allow the federal government to override and usurp their authority, by taking government grants (which always -- always -- have strings attached), or by simply accepting state or federal controls where local control used to be. Or they allow ICLEI to come swooping in under the constitutional radar with centralized non-government control (to be imposed locally, with global uniformity -- forget diversity). Our local officials accept ICLEI's "help" to implement "sustainable", "environmentally friendly" "solutions" to "problems" that We the People have not asked to have solved.
If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. ~ James Madison (Federalist 51)
The natural progress of things is for liberty to yield and government to gain ground. ~ Thomas Jefferson
Most of these local participants don't even know they're implementing Agenda 21. It's best that they don't know. It gives the useful idiots some plausible deniability.
Agenda 21? No, never heard of it. We're not doing that. What conspiracy theorist is saying that? The tea parties? Now, that makes sense!
