For starters, scroll the thread and/or search FR and read Maya's actual quotes. JMO, but except for her radical lesbianism, she sounds like a decent daughter. That's one side of the story.
The other side of the story (her parents' side) we don't know very many details about, likely because the Keyes value their daughter's privacy as well as their own. I think the only thing they ever really said to the press was (paraphrased) "Our daughter is an adult and is thus accountable for herself." Sounds reasonable to me.
It's curious to me why so many people are so interested in all the "gory" aspects of their private lives anyway. I mean, I doubt many folks would jump eagerly onto a thread entitled "Keyes goes to church on Sunday".
This story sells because many are interested in slandering and seeing harm come to a good man.
I'm more concerned with the fact the parents broke off communication with their daughter. It's unheard of.
