"people publicly posting code with comments that could make so many people feel awful, unwanted, and excluded"
Really? REALLY?
Let's call this for what it really is shall we?
A group of vigilantes being dicks to people who they feel are being dicks, because of something as intangible as "hurt feelings".
Oh please, are they feeling privileged enough? In my day bullies left bruises and broke bones, not offended and hurt feelings.
I'm offended at your offence to being offended by the word "fuck" in a comment someone else wrote. If you really want to do something, write some code. Make some art. Build something. Don't bully some other guy/girl/furry/etc into sanitising their code for the newspeak of the day.
