I realize that it was the GP comment that pushed the thread in this wrong direction, but the thing to do in that case is gently nudge it back, not shove it off a cliff.
I'm apolitical, I don't vote, and my comment was a plea to see this from a different perspective. It's bi-partisan.
And how the hell do I use the site PRIMARILY for politics? I must have tens of thousands of comments here.
I made a plea for rationality in the face of over-reaction and fear. A comment on a post about politics. I even said I was glad this was organizing the opposition to Trump; was that the problem?? This is nuts.
(Tangentially, I do think the comment threading display could be improved, but looking honestly at my own designs, I know I'm not the one to make specific recommendations.)
There have been a few similar threads in the past where people haven't seen killed comments.
