I admire his positions, and as someone who lives in the Latte Belt of Melbourne, it's safe to say I share most of them as well. However, as an employee of the national broadcaster he needed to keep his gob shut. IMO. Not because I have a problem with celebs using their platform, but because I am stauch advocate of the national broadcaster (ABC over here) and in order for it to survive, it needs to remain impartial - or at least as impartial as it can possibly be.
Fun fact. I am related to GL, disantly, through his wife.
