Totally disagree. I came here for commentary on the blog post not a cliche HackerNews trope. When I replied, his was the top comment. Honestly, guys like that need a nudge every now and again to train their filter. A downvote just isn't enough. Welcome to the community.
The solution to bad comments is not making the thread even worse, and the solution to "cliche HackerNews trope" is not to add another cliche trope with more aggression. That only contributes to taking us further into hell. The intended spirit of the site is just the opposite of that. If you're familiar enough with HN to complain about tropes, I assume you're aware of this?
