PC is sometimes used as cover for racism, but as with all things, it's complicated. A heavy dose of you can't please all the people all the time with a basic main dish of we're all human and mostly vulnerable/ culpable so take a stab at shaking hands, etc. The devil in the details often will defer to the angels of goodwill apparent for those with open eyes.
Knight was one of those with open eyes. As is Ann Drysdale, thank you.
