Svat's reply is of course excellent and highly commendable, but they did not post it until
after I posted my
cri de cœur above. The thread consisted of [svat's reasonable comment], [my reasonable reply], [svat's reasonable reply], [troll post with reckless disregard for the truth], [flagged], [flagged], where the [flagged] posts were the ones where I was correcting the misinformation.
Also, note that the person who posted the misinformation never bothered to thank svat for their careful and courteous correction and their meticulous attempt to try to DWIM the troll comment into something that made some amount of sense. This makes more sense on the assumption that they were trolling than on the assumption that they were merely misinformed — someone who was interested in the truth would surely have offered thanks for such a helpful and polite correction. Instead, it seems clear that they were only posting here to make trouble and waste the time of reasonable, knowledgeable people like svat — particularly in light of https://news.ycombinator.com/item?id=22424205.
I had already come to that conclusion because the comment was clearly based on a set of misconceptions about what TeX and LaTeX are, and how they relate to each other, which could have been corrected by reading the introductory paragraphs of the Wikipedia article for either TeX or LaTeX. If someone isn't investing even that level of care in their comments, they don't care whether they're talking nonsense or not.
We can see that the same account continues to post aggressive comments rudely attacking other users, although since I'm not familiar with the areas they're talking about, I can't tell if they're employing the same reckless disregard for the truth in these cases: https://news.ycombinator.com/item?id=22501626 "I don't see the point of your post, and frankly sounds like nitpicking."
https://news.ycombinator.com/item?id=22499637 "Don't you understand where and why are there abstractions? ... having people [referring to the person he's replying to] naively complain"
https://news.ycombinator.com/item?id=22458752 "You may quote simplistic cliches"
https://news.ycombinator.com/item?id=22459638 "Your comment is unrealistic and even absurd"
Maybe you think this is the kind of dialogue we should be encouraging on here, but I don't. I think that in addition to setting an example of better behavior, as svat did, we should explicitly call out such misbehavior and explain why it isn't desirable, as I did.
