What exactly is Mr. Shorten referring to?
Bill Shorten has never said precisely which of Donald Trump’s views he thought/thinks were/are “barking mad”. Your questions are good ones but I cant answer them. That’s part of the reason I have written an open letter to Bill Shorten.
Perhaps Shorten’s insult is best seen as a part of what you so accurately describe as the political correctness that “prevents honest dialogue and addressing the issues”.
