If you want to start a thread about Mia Farrow then you are welcome to do so.
You're really not understanding the point. Once again, I'm fairly sure you haven't read Moses Farrow's blogpost. So let me summarise it for you.
Moses Farrow says that his adoptive mother, Mia Farrow, physically and emotionally abused him and his siblings over very many years, to the extent that two of his siblings killed themselves. He describes how pleased he was when Woody Allen was allowed to co-adopt him and two of his siblings:
"I was thrilled when Woody officially became my father, since he had already taken on that role in my life. We played catch and chess, fished, and shot hoops. As the years went by, Satchel, Dylan and I were frequent visitors to his movie sets and his editing room. In the evenings, he’d come over to Mia’s apartment and spend time with us. I never once saw anything that indicated inappropriate behavior at any time."
He then goes on to explain, in detail, what happened on the day that Allen was alleged to have abused Dylan:
'As the “man of the house” that day, I had promised to keep an eye out for any trouble, and I was doing just that. I remember where Woody sat in the TV room, and I can picture where Dylan and Satchel were. Not that everybody stayed glued to the same spot, but I deliberately made sure to note everyone’s coming and going. I do remember that Woody would leave the room on occasion, but never with Dylan. He would wander into another room to make a phone call, read the paper, use the bathroom, or step outside to get some air and walk around the large pond on the property.
'Along with five kids, there were three adults in the house, all of whom had been told for months what a monster Woody was. None of us would have allowed Dylan to step away with Woody, even if he tried. Casey’s nanny, Alison, would later claim that she walked into the TV room and saw Woody kneeling on the floor with his head in Dylan’s lap on the couch. Really? With all of us in there? And if she had witnessed that, why wouldn’t she have said something immediately to our nanny Kristi? (I also remember some discussion of this act perhaps taking place on the staircase that led to Mia’s room. Again, this would have been in full view of anyone who entered the living room, assuming Woody managed to walk off with Dylan in the first place.) The narrative had to be changed since the only place for anyone to commit an act of depravity in private would have been in a small crawl space off my mother’s upstairs bedroom. By default, the attic became the scene of the alleged assault.
'In her widely-circulated 2014 open letter in The New York Times, the adult Dylan suddenly seemed to remember every moment of the alleged assault, writing, “He told me to lay on my stomach and play with my brother’s electric train set. Then he sexually assaulted me. He talked to me while he did it, whispering that I was a good girl, that this was our secret, promising that we’d go to Paris and I’d be a star in his movies. I remember staring at that toy train, focusing on it as it traveled in its circle around the attic. To this day, I find it difficult to look at toy trains.”
'It’s a precise and compelling narrative, but there’s a major problem: there was no electric train set in that attic. There was, in fact, no way for kids to play up there, even if we had wanted to. It was an unfinished crawl space, under a steeply-angled gabled roof, with exposed nails and floorboards, billows of fiberglass insulation, filled with mousetraps and droppings and stinking of mothballs, and crammed with trunks full of hand-me-down clothes and my mother’s old wardrobes.'
In other words, according to Moses's account, Woody Allen did not abuse Dylan and could not have done so. In his account, Mia Farrow did, however, abuse her children in a sustained manner over a period of years. Mia, in Moses's view, had a vested interest in painting Allen as an abuser.
Of course believing that Woody Allen is an abuser is easy, isn't it? It fits our narrative about rich, powerful men sexually abusing children. But what if it isn't true? Has it occurred to you what a serious thing it is to accuse someone of child abuse? Did you miss the recent trial of Carl Beech, convicted of wrongfully accusing people of child abuse, and jailed for 18 years? Did you miss the testimony of people who said how devastating it was to be wrongfully accused of child abuse and investigated by the police?
When you glibly, on the internet, accuse people of being "paedophiles" without any attempt to check on the facts, you are adding, publicly, to the harm done to that person. You don't think about the consequences because you don't think it matters. But it does matter. Think about what you're doing and reflect on it.
