This was written in the book Star Trek Memories by William Shatner and made me pause. But today we are seeing it happen in real time in America and yet no one is truly trying to stop it. So with this we can see exactly how it could happen then.
Hell the media alone refuses to acknowledge we have Concentration Camps in the states.
Thanks, I guess I should have explained it a bit more early in my original comment.
But I sometimes forget that the the more detailed knowledge about the Nazi rise to power and the Holocaust is naturally not as common outside of Germany (where it is e.g. an extensive part of school curriculums).
Partially inaccurate truths might as well be lies
I would even say they are often worse than lies, as spiked with some surrounding facts, the lies at the core can hide themselves. They then appear plausible, and if done right even more convincing (or at least, alluring) than the hard and inconvenient truth.
