So have I. I’ve seen it from the best of them - quite a bit. The most effective material is that most subtle and less overt. It’s a gradual process on the way to reeducation and reformulation of ideals. Take them a little bit of way, drill it into their skulls and then reinforce it later with continuing ‘education’ requirements.
Of course one can always frame an argument that no matter what it says it’s part of some conspiratorial juggernaut.
