HN tends to have waves of (for lack of a better term) "troll hunters" who come here with an attitude that everyone here is commenting in bad faith and must be called out for it. They will do it to commenters from all sides of an argument, even in cases like this where it was clear your comment was simply remembering a past event and not intended to be anything else.
I haven't figured out if they mean well and are just sorely misguided, or are actually trolls themselves here from places like Reddit where such bad faith activity actually happens in every single post.
I'm not in it for the karma and don't worry about being down-voted when I'm writing a thoughtful but perhaps contrary comment. Sometimes (like now) it teaches me that I'm out of step with the "mood" of the commons. That's fine too.
