Probably your best play at this point. One thing that has never varied is intolerance for racism. Just because the left has co-opted the term does not mean that the actual evil is all gone away. That mess has no place here. Were it otherwise, I would not be here.
Agree there’s no place for it but would like to express a distaste for his comments with reply and maybe swing his viewpoints in a different direction. There is always a possibility :-)
