What Bijou is corroborating (and what Chynna corroborated) is that this story is not new, that Mackenzie has said it for some time. However, Bijou does not seem to believe it, because Mackenzie then denied it, and because of how she thinks of her father and what that would mean about him and the rest of her family and their leaving her in his care.
I still lean toward it happened. Mackenzie’s later denial is just the kind of thing one would expect. See, she was torn about it, and was trying to make sense of it for herself, and at one moment tries to tell someone - a family member. But it is so embarrassing and shameful that she changed her mind, “Why did I mention that?”, and tried to take it back by saying it didn’t happen. It speaks of someone unsure and embarrassed and generally troubled.
I found out while I was in college that my childhood best friend had been molested by an older boy that was a close family friend. This occurred over a period of years while he was young, and my friend moved away in jr high, so we sort of lost touch a bit. Then he contacted me while he was in town because he had finally come to terms with it and was pursuing legal matters.
Here is the important point - one time we were together and saw the boy, and he made some comment to me about not wanting to be around that guy. It gave me a really strange feeling - it was like he was trying to hint at what was going on without actually saying it. I was naive and young enough I couldn’t read between the lines, and he never told me anything directly, but even then I was trying to understand what he was meaning about the guy, and asked for clarification - was the guy bullying him or what? Didn’t get it then. I mean, I was picking up hints but not enough that I felt sure of anything. What makes the situation worse is that my friend’s mother actually caught it happening once, but the boy said it was just the one time and she apparently was naive enough to accept that.
Why did I bring this up? What does it have to do with Mackenzie Phillips? My point is that screwy ass shit happens and the people around can be oblivious, and even in active denial. People can be in pain, be troubled, and not be able to turn to anyone - even a best friend or parent - for help. They can try to reach out, and then change their mind out of embarrassment and shame, and so not get help. They cover up out of fear and shame when they should be crying out loud.
Yes, it would certainly be easier to believe if someone stepped forward and said “Yes, I knew it was happening, but hey, they were consenting adults, it wasn’t my place to say anything.” Without that, I’m sure a lot of people are going to withhold conclusion, or actively refuse to believe. But who is going to come forward? Who out there would have known and not said anything to them at the time? Who is going to come forward and admit they knew that was occurring and did nothing about it?
