I will just point out this basically proves my point. The question was what norms changed. I said a candidate won an election and some people won't acknowledge that which goes against previous norms. This is a simple fact confirmed by basically every credible news org in the country, but it is now apparently enough to be considered a "garden-variety political flamewar post".
I swear I am not trying to be a jerk, but what were the many markers of a political flamewar that I used? I know politic topics have been getting heated on HN lately and I am probably more guilty of participating in that than the average user. However I do try to stay on the line of what is allowed here and I legitimately don't know what you are objecting to in my comment.
I also don't know how this is a disputed fact when basically every news source from MSNBC to Fox News and practically every world leader from Angela Merkel to Xi Jinping all agree on it. I don't think there is a single credible source that disagrees with the outcome of the US presidential election.
I don't think my comment would have been considered to have markers of a political flamewar or considered anything but a fact if I wrote it 4 years ago about Trump's victory over Clinton. That is basically the entire point of my original comment. Our standards have eroded in the last 4 years.
