It's interesting to see that the only account complaining about HN politics was created 20 minutes ago. Maybe there's a lesson in there somewhere.
Yes, I think more and more we are seeing that. The post was flagged, but it's worth a discussion.
Anecdotally, under previous names, I've noticed that before on HN thoughtful conversations could happen when it came to politics. I'm finding less and less of that to be true, and more posts are becoming flagged/flame wars.
Still, labeling and name calling is rather the exception and as you too observed, gets flagged quickly as such. My point was that some accounts seem to be created for the sole goal of name calling. Oh well, I'm happy they're only a few.
Seeing debates about Trump/Pelosi on here is very saddening. Anecdotally it seems that discourse on politics here has become much less of seeking understanding and much more snarky comments and evangelizing beliefs.
