Did not see the doc, do you have a link?
I know one was Esme from GOT who is a difficult woman, a staunch supporter of metoo, the no facts version of it, and despite the "horrible" time she had with him she went away after settlement. One woman was found lacking enough substantive evidence IIRC. The other two I dont know... But I do remember Rose Mcgowan, one of THE MOST annoying, accusitive, metoo fanatics giving Manson a green light and defending him. And shes always the first to point fingers, its basically all shes known last few decades for, wokeness and metoo. Or Dita, a strong feminist, also been with Manson for years and defended him.
You never know... but Wood always seemed a bit off her rocker IMO. Though I know how good some people are at gaslighting others and some easily swayed. And the change in times, the unequal power scale between men and women, Mansons harsh fetishes, Its not surprising that some women who were with him might look at that time of their lives with regret or a feeling of powerlessness. But thats looking from todays perspective. IMo its better to leave it be and people go forward with todays normatives which are giving women a lot more say. Better than destroying people for being different in different times.
