Not everyone in Mackenzie's life is as supportive as Valerie. Oprah says some of Mackenzie's family members are concerned that High on Arrival will defame John Phillips' memory.
"Interesting that they're not concerned about how it might defame me," Mackenzie says. "I'm taking a huge personal risk telling this story, and I have to say that I loved my father. I still do. … I know for a fact that I am the only daughter that this happened to, and I don't know why he chose me to visit his demons upon."
Mackenzie says families often try to sweep incest under the table. "For some reason, [people] think: 'Let's protect the abuser. Let's protect the reputation,'" she says. "I, on the other hand, firmly believe that if he could have done everything differently, he would have. He never set out to harm me."
Despite the love she still feels for her father, Mackenzie says what he did was wrong. "No matter what kind of incest it is, it is an abuse of power," she says. "Whether it be consensual or otherwise, it is a betrayal of trust."
