It only "made it out" because (thankfully) not all communication has yet to be fully gatekept through "fact checkers".
In the world you are advocating for it would have never made it out.
If that doesn't scare the utter crap out of you I would strongly advocate you are GROSSLY ignorant of history and need to do some serious learning - especially about how a certain party in Europe happened to come to power before world war II. And if you don't think what we are going through right now isn't a precursor on that level - again do some serious reading (preferably from books with copyrights before the 1990s and not online) about the rise of said party. The parallelism going on right now is pretty breathtaking when you stop and really look around.
We've been watching (and really "enjoying" - although the shows are really well-made it's depressing knowing what actually happened):

So? The idea made it out, though it's far from proven. In any case social media chatter and speculation about the idea like that has little value.
And this is something I'm totally fine with. I think it's totally in the service of truth to let an idea cook, before it's blasted to the public over social media at a loud volume.
