"A child has an abusive or perverse role model, which in turn leaves the child with no spiritual covering and leaves them open to perverse demonic spirits, these demons confuse the gender and identity of the person."
No, homosexuality has a significant genetic componant, it has no demonic componant. Abusive or perverse role models can have long-term effects, but there is no evidence showing homosexuality is linked to poor role models.
A person engages in homosexual sex out of enticement or curiousity and then a double wammy occurs."
Uh huh, they either find out they're homosexual or that they're not. Some "double wammy."
"They commit a gross sin against God,"
As you, or anyone else for that matter, haven't shown God to exist, sin does not exist, therefore, homosexuality cannot be a "gross sin against God."
"plus, there is a transferance of a perverse demon from one person to the other."
Here again, you presume that demons exist, but neither you nor anyone else has provided any evidence to support that assertion.
"I have been accused of over spiritualizing, but I believe this sort of thing is very real."
I would like to be the next to accuse you of "over spiritualizing." I'm sorry that your mental capabilities are such that you believe in demons, God and other imaginary beings.
