“I would have thought that Agenda 21 was pretty much dead across he US. Strange story.”
You’re forgetting how the left works. Nothing goes away. Nothing is ever actually defeated.
All they ever do, if one of their hopes/desires/dreams don’t come to immediate fruition, is to lay low for a bit, think up a whole new batch of slogans, then start throwing said slogans against the public wall until they find one that sticks with enough idiots to start agitproping toward their goal, again. And if necessary, again. And again. And again...
The leftist laying low technique you point out was best summarized by Lenin: “Two steps forward, one step back.”
Well, I’ve seen stories about locals coming together to derail Agenda 21 and based upon those reports, they’re winning against it. People need be vigilant to stop it.
