The reason I tend to object to these things is that bikeshedding isn't free, it creates work and technical debt. That raises the bar for changes we ought to make, and I think it raises it quite a lot higher than objections which are frequently specific to the US and are largely imaginary (which is my honest interpretation of most of these changes).

That said, "genocide" is clearly unnecessarily provocative. It's also not an industry-wide change, it's just one function, so this particular change seems sensible to me

Fuckin exactly.

"It's stupid to change it to main, it's just words"

"Oh, so since it's just a word change I guess you shouldn't be bothered by it."

Angry NPC face

The people who legitimately hold the view that it's just a word might be a little frustrated at the small bit of extra work of needing to change their scripts or code that uses those words to the new words, but otherwise no big deal. But a lot of "it's just a word bro" folks actually do care and just like to pretend they do not for clout, because caring is for lame losers and being able to falsely present yourself as a previously-neutral party now moved to care by how stupid something is can hold a lot of weight when convincing others and make you feel cool.
