When people make comments like this do they seriously think providing a single example tears down the concept of systemic issues?
This is a "it snowed today, so global warming doesn't exist" type of comment.
No, this is a troll looking to diminish the value of this community. Best move is not to comment or engage in the future. Downvote and/or flag. Or contact dang at HN moderation.
Or, ask curious questions. Trolls hate curious questions.
