Both PC and H&S are designed to enable discourse, activity and cooperation not to stymie it. Captain Swing - I am sorry, sir, but those words make you 'of the mob'.

PC (not H&S so much, rarely so) is just as easily used to shut down debate, discourse, and cooperation. Disagree with me and I will call you an Ist. Convince the rest of us that that is never true or, at least, so rarely true that it can safely be ignored. Unfortunately, your words so far here leave me thinking that you are one of those that can't, don't, or won't recognise that this can even happen...
