HN norms apply to posts and posters on HN. They do not apply to TFA, and certainly not to uncertain references in TFA. Even so, I started this thread by scrupulously allowing that the original allegation about the calendar bone might have been phrased in terms of "humanity" rather than "man", since after all TFA had no link to that allegation. In subsequent replies in this thread, I have only commented on the inherent sexism of a general theme of writing in English, and have at no point addressed that to anyone writing here. I have not in this thread "looked for offense", "created imaginary enemies", "argued in bad faith", "felt insulted and discriminated", "invented issues", or done any of the other silly things you've accused.
ISTM it is at least possible that existing idiom might have harmful effects on portions of the population. If those who suffer those harms aren't allowed to complain for reasons of decorum, how are their lives ever to improve? More importantly, how are we to know that we're harming them? Wouldn't we want to know that, so we could stop?
And isn't it wonderful that all my posts in a 20-hour-old thread on a 2-day-old flagged article have just been downvoted. Sockpuppet accounts for downvoting are discouraged on HN as well. [EDIT: removed opinion]
