It’s probably too hard to rid the term political correctness of its negative connotations—among other things, it is often conflated with being dishonest or having low integrity, which in my opinion is a drastic generalization of a few bad examples—but I do wish we can somehow preserve one aspect about it: that you can simultaneously deliver hard feedback and articulate it in terms that would make a person other than yourself want to hear it.
As we often say to define cultures of kindness: to be kind is to say things respectfully but directly to help someone else grow. To be nice is to just say things another person wants to hear even if it is different from reality and is going to hold them back.
