Nope. After Covid, I get it. The vast majority of people will do what they’re told and hate who they’re told to and dob their neighbours and colleagues in for even the tiniest scrap of power-associated dopamine.
Nitpicking a bit -- some will, but I think most people require an intense dehumanization/redefinition campaign first. I like the
ten stages model. We had that with COVID, of course. Plenty of the Milgram experiment folks who ended up pushing the button expressed misgivings first, just not the (IIRC) three times necessary to end the experiment. I feel a bit bad about poisoning the rats on my property, but I still do it. People underestimate the power of reframing when coupled with pervasive social pressure. There's a reason the Jews are "vermin", the Tutsis are "cockroaches" etc. There may even be something special about our instincts toward contagion at play in the subconscious.
I knew a family of leftie folks who were hard core anti-vaxxers pre-COVID. They got their COVID vaccines ASAP, of course, but they also frequently ranted to me about how stupid, how ignorant, how awful the unvaccinated are for killing all those people, the whole works. There was absolutely dehumanizing language and suggestions of restricting basic rights, and while I don't recall them suggesting concentration camps, it would have fit right in. It was thinly veiled contempt of the political "other" of course -- what they really wanted was the unrepentant red hats punished with state power as everyone stands up and claps. And no, I didn't ask, nor encourage, the topic with them.
What's funny about this story is that once the propaganda subsided, they returned to their pre-COVID anti-vax views, going so far as to seek a medical exemption for their kid to attend school without an MMR vaccine, and send them to some weird paid homeschool thing (no clue if this is legal where they are) when that didn't work. They even stopped getting their COVID boosters a year or so ago. They rationalize it all as "doing their research" and "it depends on the vaccine".
You can fool some of the people all the time, and all of the people some of the time, but not all the people all of the time -- but you can usually intimidate those ones into acquiescence.
I don't know whether I'd turn in Anne Frank or not. I really hope I'd be wise enough to recognize what was going on, especially when I was younger. Plenty of people did recognize it, but it's unconscionable arrogance to assume I would be among them. Remember, she wasn't being rounded up to be killed, just "resettled to the east". Propaganda provides comforting lies in the face of horrendous reality.
