I heard the tales of Nazi Germany first hand from my German mother. Many of her generation are gone or going fast. There’s no one left to explain what happened.
One thing she said recently is that your neighbor will be the one to fear. When push comes to shove and it’s a matter of whether you’re inside or out, they will chose the path of least resistance.
I agree, thankfully the neighbors on both sides of me are older HMong that came in the first wave asylum seekers, I believe that they will be an early warning system. If I see them packing up I will follow suit.
