This is what is called Cancel Culture. It is really not OK to be offended on behalf of someone else. When people do this, they are infantilizing (is that a word?) the supposedly offended and some of them don't like that behavior.
But go ahead and change your git repository to "main" instead of "master" just in case someone thinks it's some kind of slavery reference (everyone will update all their documentation and tutorials right?). Next we can work on your cars brakes (master cylinder), anything that involved master templates, certain golf tournaments, and what on earth are we going to do with all those masters degrees?
