In the very first reply, dang explains that the account was banned for repeated violations, so it's not just the content of that particular comment that got it flagged, but rather the account itself was banned so the comment was marked dead.

Frankly, however, if the commenter had wanted to create a discussion rather than troll, they could have used a vastly different tone. Just because there might be some interesting topic buried under the layers of sarcasm doesn't necessarily redeem it. If you want to discuss it, maybe you could elaborate on what you found interesting and post a separate response to the parent, and do so more civilly than this comment.
