What it is oriented around is intellectual curiosity. There's little of that in current discourse about the word "fascism", and a lot of flame-throwing. It's the partisan frenzy of the moment. I imagine that's why users flagged this submission, despite Umberto Eco being perennially interesting and welcome here.
Is a touchy subject on here, for some peculiar reason.
Now I wonder what that could possibly be.
Had you taken a few seconds to check it before posting a glib swipe, you'd have seen that it's obviously untrue: https://hn.algolia.com/?sort=byDate&dateRange=all&type=story.... This very essay has had multiple discussions on HN in the past:

And that was the full original essay, not the Utne Reader's digest version. The issue here is not "you can't talk about fascism". It's that the talk going around at the moment is predictable partisan flamewar and name-calling, with the F-word being the biggest tomato thrown. It's that which we don't want on HN. When thoughtfulness returns to the discussion, I'm sure users will stop flagging submissions like this.
Under present circumstances there is little chance that a thread like this will be motivated by intellectual curiosity rather than partisan passion. Users who attempt to do the former get piled on with heapings of the latter. This very essay has been discussed with curiosity in the past (https://news.ycombinator.com/item?id=12173823), but I don't think that's why it's showing up now.
