I have read your post Brandon.
Here is what you have stated:

Birth Defect=a defect that is present at birth. Can occur during fetal development or through the birthing process.

Purely physical and not learned=there is a genetic predisposition for homosexuality completely independent from any environmental influences or individual choices.

Go either way?
If homosexuality is, strictly speaking, a birth defect, or something innate but not learned, then how might someone go about "going either way".
If homosexuality is, as you propose, a birth defect, then there is a predisposition toward homosexuality and their orientation is predetermined, not by environmental influences, rather, by genetics.
It's analogous to arguing that someone may, at birth or afterward, become either male or female.
Brandon, you are incorrect in your thesis. If homosexuality is a "birth defect", it is not unlike an individual's gender and it will not be altered by the environment.
When dealing with genetics, all maters of choice vanish.

Unless you are referring to a child being instructed while in the fetus as to what their sexual orientation is, you have contradicted yourself.
