Didn't watch any of the Daryl Davis vids I linked there, did you?
How about, we get a few more Daryl Davises around and it wont get to Nazi Germany level again.
One man, over 200 people de-nazi'fied, many (I presume) even turned any of libertarian, anarchist, or (genuinely) socialist. If it were all [Edit: (or even if not, since pretty much anything's more positive than Nazi)], could even say that's an over 400 people shift to the positive.
How many Nazis have you stopped being Nazi by killing them? And how many more Nazis did that make, as they rose up in lockstep vowing to end you and anyone like you all the more, in vindictive retribution?
Or is that the plan? Keep psychologically driving them harder and deeper into Nazism, and more of them, until we do end up in a Nazi Germany level again?
[Edit: PS: Mattias Desmet's book, The Psychology of Totalitarianism is a superb read on the topic too. Save us it can. Don't let them reach their dire tipping points. Keep speaking up. Shatter their illusion of the one true way.]
