It's any author's task to make their cases in a way so that people pay attention. In this case, this maybe failed. As I mentioned in my other comment: Using terms such as "offensive" when trying to make a serious point to fact- and argument-oriented people (which one typically finds on HN) might not work very well.
It's better to be critical of the author's approach to making the case than to assume that the problem are the readers.
would you think this is a universal response (and therefore problem) or perhaps only among a certain readership? would an author not have to take into account the average response to their phrasing (or that of the audience they address)? if this is not the hn readership, then I would think a word like 'offensive' is comprising a lot of meaning in a concentrated way (ofc you can still disagree with the judgment, that the scenario is truly offensive).
