If you can google, and get more than 20 million hits on Agenda 21, maybe that's just one of his reasons. Subjects like the one we are discussing will be prohibited.
Agenda 21 is a bit old. The implementation isn't by UN action, it's by fed through local zoning, land use, code, EPA, ect rules. In addition, requiring planning for everything drives operating expenses up even further. The plans aren't allowed to be flexible either.
Folks never really see the connection. It comes in little peices and by stealth as buried items in budget bills. Required land use planning came as an item attached at the last minute to a budget bill at the end of legislative session. Most have no interest anyway, because they have nothing at stake and are shown what they have to gain in this taking of other folks property.
Then we need to discuss it more. Not only for the sake of defiance but to get more people to learn about it. Even I have not heard of A-21 until this thread.
