“25-year-olds have the intellectual wherewithal and social competence”
They were brainwashed—they can be un-brainwashed one at a time.
In addition some are more brainwashed than others.
There are many subtleties to this game—winners break the rules and find niches that work for them.
I sincerely believe that one would have more luck plopping someone from the present down in 1938 Germany, and expecting him to "stem the tide" by holding "earnest conversations" with individual Germans.
You are talking like it's possible to isolate a single young woman and "work on her" and "turn her around" - independent of the lifetime of indoctrination she has been subjected to and apart from the sea of opposite impulses she is being constantly fed by her equally warped peers.
