“The Democrats”, maybe not. “Leftists”, however defined, certainly did, and the difference might not be apparent, nor important, to the typical voter.
“Nazi” is used as a rhetorical device, a label to assign to anyone not conforming to a certain set of beliefs typically described as “woke” (see fediverse, especcially #FediBlock hashtag if you don't believe me). I took liberty to parrot that rhetoric, not to use it in the real meaning.
As long as this is dismissed as “ghost stories”, HN is still in denial phase. While the decision to censor the data is wrong, whatever we think about labels (people not agreeing with a set of categories can probably filter/tranform on their own), I think is important to realise, what moves the people who do such things, to get at least basic understanding.
Don't you see how the turn of phrase "Leftists, however defined" is exactly the kind of storytelling that confabulates the phantom internal enemy that Fascism relies on to justify its advances?
I can only imagine what circus of demons you're imagining fit into this group of "Leftists, however defined."
Furthermore, Nazism is a very real and hiatorically bad ideology against which we must be vigilant.
So, you are comparing ghost stories to history books.
