Ah the “book” thing again.
Frankly, I don't see how anyone who looks into the history of the “book” could come away thinking it was somehow a perfect representation of what god (or anyone) wants.
For the sake of argument lets remove the “book” equation for now.
(Don’t want insult anyone “book” ok)
“if you learned that poison is lethal, even nobody tell you not to drink it, under yout justification, are you going to drink it anyway?”
Normal answer is big No. Yet some still choose to drink it.
The justification : The lethal dosage of the poison and the context of the poison it represent.
Is it possible TS know if it is taken in small dose it will not kill him. Heck he might even built up some immunity against that poison and possible some other B*** S*** as well.
I mean early human started eating raw meat before fire was even invented, of course some die due to poisoning, yet some human learn from it and adapt to it.
As for why some take the poison, maybe they saw something that is worth taking it.
-Anyway it is my personal opinion.
But what make people against the homosexuality is what written in those books. otherwise it can be a lifestyle with nobody finds it is a sin. no problem with it after all.
