But until someone can prove me or my Religion wrong on the issue, then I'll continue looking.
If it's all about your religion, why bother with the natural and normal fallacies? Why not simply state:
Premise 1: I believe the bible to be accurate about what it describes as immoral
Premise 2: The bible describes homosexuality as immoral.
Conclusion: Therefore I believe that homosexuality is immoral.
At least you'd have valid logic.
The arguments you do present about normal and natural are simply not valid logic. They are attempts to use things
other than the bible to justify your beliefs. You don't need anything more in order to justify your
beliefs about morality, though.
Where you
would need more than just the bible is when you take your own moral beliefs and attempt to influence legislation with it. This is why so many arguments against gay marriage are fallacious. Those who oppose gay marriage, in many cases, do so based entirely on their moral views which stem from the bible or religion.
Yet they know a biblical basis will not be accepted for legal purposes, so they try to come up with other arguments, even though these arguments are
not the one's which convinced them that homosexuality is immoral and "wrong". This is why those arguments are often illogical.
But if your views are based on the bible and religion, just stick with that. Say "I believe homosexuality is immoral because of my religion. I don't
really care if it is normal or natural. As long as it is considered immoral by my religion, I will
always believe it is immoral."
That's an honest argument because, ultimately, that's what's going on. Your views are fixed on this. I would guess that it would take nothing short of the Pope himself saying that homosexuality is morally acceptable for those views to change.
