Look, who doesn't like Tom Hanks, but frankly given how this is so endemic in Hollywood and he has gigantic power and influence he is exactly the type of person who should have stood up. For goodness sakes Meryl Streep applauded Polanski after it was known for certain he had raped an underage girl. Hanks has no problem hanging out with Streep, or with Hilary Clinton who deployed the worst possible blame the victim tactics, in and out of the courtroom, when defending rapists. Or Bill Clinton who is as disgusting as Trump when it comes to women.
The issue with Hollywood is not that this happens everywhere (any executive in my industry sector would have been fired long ago for assaults) it is that Hollywood does so much finger-pointing and is very deeply hypocritical. This story has legs not because Weinstein is just a part of Hollywoodn but a central representative figure
