For those of us in the states... Other countries empty out 2 litre soda bottles to measure out their gallons of gas. its an extra step, but pretty much the whole world has decided base 10 is better for some reason.
I support teaching all kids what it takes to exist, regardless of gender.
I just popped in to say that back in the long ago, in my family, only so much help cleaning up was tolerated from men-folk before they were exiled to football on TV so the women could sit at the kitchen table and talk.
Trying to assist in cooking was nearly impossible by anyone who wasn't my grandmother or the aunts that had been cleared for assistance.
I was taught to cook and clean by these same people, but it was clear that at big family meals like Thanksgiving that most of us were in the way if we tried to assist.
I guess what I'm saying is, for sure teach everyone all of it, but big meals might not be the best time. (depending on size of family and a variety of other factors).
If the OP had a mechanism to opt-in to aggregated comments, rather than individual community comments, there could be an identifying notice that the comments of that post were being "hosted" in whichever community on whichever instance and were governed by their rules. Essentially, commenters would be guests in that forum and be expected to comport themselves accordingly. I don't think it needs to be complicated for mod teams.
Consolidation is one of the things the fediverse tries to mitigate. I see your point, but federated services need some amount of redundancy and autonomy for the whole thing to work.
In order to be civil, thoughtful, and graceful, a person needs to reflect and understand complexity. The platforms of the internet incentivise the opposite. Extremity is louder than resonability so it floats to the top of the discourse.
Additionally, seeing 100, 1,000 or 10,000 people on a platform, from around the world, express shocking or anti-social viewpoints represents an infinitely small sub section of the population. A group that includes provacateurs, bots, nation-state actors, and wing-nuts.
The real trouble comes from others who aren't taking time to reflect, who see this content every day and begin to believe that it must be valid because they keep seeing it. Slowly they twist and adopt pieces of rhetoric because there isn't enough of a counter balance of opposing views sharing the same weight in their feeds.
The original idea was that the "trick" was the default (some type of mischief or vandalism) but the costumed (annonymous) tricksters would give the person a chance to be spared by offering a "treat" instead.
You're just not trying hard enough
