I realised the deceptive but powerful communist rhetoric that often well meaning but naive people fall for. And when you try to explain the deception directly to them they cannot see it and stare blankly back as if under some kind of spell or brain washing.
I found this effect long ago when dealing with brainwashed people here in Argentina. The most terrifying effect I found was that even if THEY themselves arrive to the conclusion that the ideology, ideas and practices are flawed, out of emotion they will reverse that logic process and get back to their first most flawed argument like if nothing happened at all. I found out that you first must make people emotional about your ideology, to then proceed to use logic to seal the deal.
