The point seems to escape you, it isn't about the sensitivity of the issue, but about if the behaviour is changed or not.
You're better than this - if you are a moderator then learn to ignore these (it won't be the last one you see in life :)).
If it was my call, I'd go even further. If you're unwilling to put your love of software development before your arbitrary personal opinions, you shouldn't be trusted in the SDLC. It's a petty rabbit hole that ends in people writing overly restrictive CoCs instead of pounding down the offending users with a mallet. Make an example out of them.
Also, apparently the discussion forum post (or github PR?) has been removed so there doesn't seem to be any good evidence either way. Looking at srid's PRs, mentions, discourse etc, it seems all ok, can't find any of these toxic derailments and what not.
