I was first subjected to a Delphi treatment back in 1994 and spoke about it at a Freedom 21 Conference hosted by Henry Lamb.
My being an often irascible and stand-alone individual, even had I known of such countermeasures and practiced them, it might not have worked even with prearranged and practiced allies.
Apparently something similar to my failures have been true for many others as well, because the Progs have advanced far too well despite this knowledge. So? How often has it worked? Seeing the power of the GOPe and the weakness of conservative pubbies, I'm surmising: not yet enough.
The Collectivists work well because they are NOT individualists first. They want power, individuals mostly want to be left alone, tending only get involved when push comes to shove. I always wished I knew what path worked to get more of us to take a long view so as to necessitate involvement. I regret I gave into despair after many failures. I am to blame for those failures. They were mostly due to my inability to build such needed blocs before confrontations with the enemy.
And now, I'm old and tired. I wish it were not so, but even when young I tended to write with a Jeremiad tone. My failings need not be those of the next generation, and I hope it learns from errors such as mine. I surely wish you better success.
I sincerely hope you can convince younger people to do what I could not persevere at.
One more thing though. This discussion of counter tactics was devised before the Left started to deploy more fascistic types. In this day of shameless lying, the "knock-out" game and jihadi-like masked thugs, all but feigned niceties have been pretty much disappeared. Any countering group need to have strong security even as it attempts to appear unconnected to each other, else they are apt to be targets as individuals going out the door (and maybe even on a meeting floor).
We have arrived at trying times.
