That's the thing about this #MeToo movement. It's not court and nothing is proven but it can still ruin someone's career. Each time it does, you have to hope the accuser is on the up and up because we can't prove anything one way or another. So I don't blame those who want to wait to say "yeah, he def did it".You should always know the facts before you crucify someone, unless it's on the level of a Kevin Spacey or Bryan Singer, where everyone in touch with the zeitgeist knows and understands.
In college, a teammate of mine was accused of raping a girl, and it completely ruined his life. He was one of the nicest guys I've ever known, and still is to this day. At a party after a big game he went out and ended up going home with someone. Seemed completely consensual from our point of view. Few days later the girl came out and said he raped her. We couldn't believe it. Everyone on campus crucified him. He got kicked off the team, lost his scholarship, and was a shadow of his former self for quite some time. Cut to two years later, that same girl is at a party with us and gets in an argument with another teammate who won't sleep with her. She gets angry, and yells that she'll do the same to him what she did to the other guy and lie. We were upset, but there was nothing we could do about it.
These stories happen a lot. Happened to my best friend's dad too. One of the best men I've ever met in my life. I'm not saying sexual assault and rape should be looked at with a skeptical lens, but to ignore the fact that people do have the capacity to lie is bad. Men lie, women lie. Get the facts first. Then deal the Justice.
And another thing, you always hear anecdotal stories like the one you posted. I've experienced the same situation: friend was accused in England of rape... it was consensual and I witnessed the before an after. They went in together and came out together laughing. He went on to have relations with her good friend and she claimed rape a few days later. I had to testify as to what I saw and he got off.
But for as many times as people say it happens, it doesn't seem to be reflected in the numbers of false claims I've seen posted around here. It just makes me wonder how accurate those numbers are and the numbers for sexual assault in general. This #metoo movement has to show that they're off... that's a lot of unreported cases.
