Please don't frame comments like this as sneers at the community. Perceptions of the community are extremely subject to bias (see https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...) and it detracts from the substance of your argument. The community here is simply divided on divisive topics—reality is that tautological.
It's disingenuous to frame my comment as a "sneer", and censoring (via pushing this comment down, when it was previously the top comment of this thread) mentions of community self-introspection is doing this community a disservice. If it truly is not a bubble, then my post would not have been upvoted to the top comment of the thread. Clearly it was something that people wanted to discuss prior to your intervention. Living within an echo chamber is a bad thing, both for the community and for society in general, and HN should be able to discuss that without your intervention.
Your comment was previously near the top because newer comments always start near the top. It's gone down because it has failed to attract enough upvotes and newer comments have taken its place. It doesn't take a moderator shadowban for a negative comment to lose ground on HN.
I know how HN works, but thanks for explaining it. New comments are only given the top spot for a small time period. My comment was at the top long after said time period, because it previously had more than enough upvotes to stay at the top (in fact, it actually had been knocked down to middle-ish of the thread, and then garnered enough upvotes to again be the top). As soon as dang commented, it suddenly was at the bottom.
