Please don't pick the most provocative thing in an article or post to complain about in the thread. Find something interesting to respond to instead.
For a reader clicking on the post thinking there's going to be a good discussion, they get the first post forcing gender politics irrelevantly into the discussion, then a bunch of stupid follow-up meta discussion. Even if they can collapse it, it's already ruined the threadAlthough in this particular case, I think you're in the minority in believing that the original comment was provocative.
“In combinatorial mathematics, the ménage problem or problème des ménages asks for the number of different ways in which it is possible to seat a set of couples, labeled “A_n” and “B_n” accordingly, at a round dining table so that the A and B alternate and no two couples are sat next to each other such that A_n = B_m”.
Idea stolen from this video on Gale-Shapley, which is also typically presented in a "gendered / heteronormative" way (but doesn't have to be): https://www.youtube.com/watch?v=fudb8DuzQlM.
I mean there are so many possible examples, right? Anything where you have pairs of partners.. bridge, tennis doubles, etc.
