Hollywood has known for years that Weinstein was a sexual predator. In 2006, singer and actress Courtney Love publicly warned young aspiring actresses to avoid him. In 2013, comedian Seth MacFarlane joked on stage at the Academy Awards about Weinstein's predatory nature. Actress Rose McGowan, who says she was raped by Weinstein, has condemned Ben Affleck, himself the subject of sexual harrassment claims, for maintaining that he did not know about Weinstein's behaviour (incidentally, McGowan made the claim on Twitter and the social messaging service responded by suspending McGowan's account, a demonstration of that company's poor judgement when it comes to who gets suspended and who doesn't).
One could excuse Hollywood's convenient blindness where Weinstein is concerned if it wasn't for the industry's appalling hypocrisy. The American film industry presents itself as a paragon of liberal sensibility and tolerance, most recently in the attacks of many of its most prominent members on President Trump (e.g. Merryl Streep's speech at the Golden Globe Awards), but the Weinstein affair reveals that misogyny and abusive behaviour in the industry is far worse than anything Trump might have done.
The holier-than-thou self-congratulation of the industry is sickening. Whether it is director James Cameron on Donald Trump or Leonardo di Caprio on climate change, those who have made a name for themselves directing or acting in films seems to think they have some special sanctity on the political and moral issues of the day. My view is the opposite - their privilege and fame has often distorted their perspective and they have little idea of the challenges facing the ordinary people who fill their box office coffers. They cannot understand, for example, why so many Americans voted for Trump, because they haven't suffered the economic and social privations of people in the 'fly-over' states whom they hold in such contempt.
It is is the self-righteousness of Hollywood's leading lights that makes Weinstein's crimes all the worse. Perhaps if they all had a little humility, we could condemn Weinstein as an isolated fiend, but I am sure it is their very arrogance that enabled Weinstein to get away with his behaviour for so long.
