The Anita Hill hearings had some pretty decent entertainment value. If nothing else, it was worth it just to hear Orrin Hatch talk about Long Dong Silver and pubic hair on coke cans.
As for the original post, societies and people evolve. Back then, women like Willy and Hill weren't necessarily believed in he said/she said situations, and even if the unprovable assertion were true, it wasn't quite the disqualifying event that it is in today's society. It has been like a slowly building tidal wave over the past few years beginning with Cosby. Why now? That's like asking why a video on youtube went viral. We're in a different place and time and more receptive than we were 25 years ago, and after Cosby, Trump and Weinstein, it has just snowballed.
And let's differentiate 2 separate things - sleeping around v. unwanted sexual assault or harassment. Everyone has always known that in Hollywood and Washington, a lot of folks have always had affairs or was sleeping their way to the top. And I've admitted here that I didn't believe the Willy and Jones groping accusations at the time, knowing that Bubba was getting himself a lot of free tail and reasoning why would he take stupid and unnecessary chances by groping women when he had most any woman he wanted anyway. And back then I can remember friends and old girlfriends sharing molestation stories when they were kids, but I don't remember any sexual assault or harassment in past workplaces or hearing such stories from friends. However, I've had several friends share sexual harassment stories over the past year or so. I really hadn't realized how rampant sexual harassment has been over the years in all kinds of workplaces, but with the recent spate of stories about pols and Hollywood folks engaging in it has at least anecdotally with me brought out a lot more discussion at the water cooler or over drinks or dinners.
