Callwaiting - Does this belief spring from the information that some gay adults were molested as children and that the assault was causal to their later identification as gay?  

I often hear the argument that sexual assault in childhood by a same-gendered adult led to the child's homosexuality. 

But my take, as a former child protective social worker, is that kids get targeted by pedophiles because they are vulnerable or unprotected in some way. Being different-which gay kids often are-can result in kids being vulnerable and unprotected: isolated socially through rejection and neglect by parents, friends, churches and schools. Pedophiles seek a child upon whom they can act their own sexual needs; some prefer girls, some prefer boys, some don't care: all are looking for a child vulnerable and isolated in a way that will allow the adult to commit a crime undetected. That is why gay children are frequent targets: WE make them vulnerable to abuse.
