More context please?

The Post-WW2 reeducation programs for denazification were probably justified. Like showcasing the horrors of the nazi regime by giving people mandatory tours of the concentration camps etc.

I don't. Who would? This sounds like the plan of an evil dictator, a deranged cult leader, or a cartoon supervillain.

I don't.

Neither censorship nor reeducation would be generally voluntary, so somebody would have to be given the authority to mandate them.

There's a simple test then for whether or not something is a good idea:

Think of the person or people or political party you consider to be the greatest threat to others. Then think of what they would do with that power.

Because it doesn't matter what the original intent is - if such a power is granted, no matter to whom or for what, those people WILL, sooner or later, get their chance to wield it.

@MGN22 One can always try to justify using information control tactics as a way to manipulate in favor of what is right, correct or just. But using manipulative tactics for 'doing good' cannot guarantee that they will not be used, in return, for 'doing evil'. It just means someone else decides for you what the narrative is, gets to decide what is right or wrong, and gets to decide how you think, rather than you being able to get ahold of all the information and making that decision for yourself.
