As to speculation on the internal state of the Keyes family, I don't want to go there. I will say, however, that every person I know who experimented with homosexual behavior, to a one of them - all experienced difficulties in their relationship with the father. In the case of many dads, it's not physical or sexual abuse. It can simply be a result of absence/unavailability/distance.
As someone pointed out, she could be the prodigal daughter, but if she isn't, then it's a bigger problem that needs to be looked at from both a conservative perspective as well as a faithful perspective. To much of this is happening to young folks who have had the proper faith based education and come from strong faith based families as has Maya. Soemehow, there's a disconnect and something larger is happening or being exposed.
Women will often experience that with their moms and boys with their dads. That's why they turn to a same sex relationship, to fill the void.
I think it can become rooted in a person who is suduced or raped by someone at an early age.
