I'm really surprised to see this on the front page. Usually stories like this move off the front page in minutes. It's not because of flagging though. I had asked the question on a previous article which disappeared off the front page in minutes and Dang was kind enough to provide an explanation
https://news.ycombinator.com/item?id=43487014The relevant bit from his explanation was
"Mostly that's because this general topic (His You-Know-Whoness) is the most repetitive/indignant one that HN has experienced in recent months. We're trying to avoid that, not because of the specific topic, but because those qualities (repetition and indignation) are the opposite of what the site is for, and destroy what it is for."
So, contrary to popular perception, it's not the flag/downvote brigade which causes these stories to disappear off the front page.
