Being gay is a choice just as you chose what will you wear or eat. Is it a good or a bad choice, is not on us to decide, but it is a choice. Not a genetic mutation that makes them gay.
I said there was nothing about killing gay people. Hating them is something much different. Every religion considers them abominations and as long as they only remain on hating them, who gives a fuck. Now Israel on the other hand finds hating muslims a little bit to weak, so they decided to try torture, slaughter, humiliation, building walls and letting them starve to death. And that little war you mentioned, it happened just because the rest of the muslim countries could not stand seeing those poor people tortured to death. And they would free them if the USA have not interfered and threatened to attack Egypt if they did not retreat.
I could recommend you a bunch of clips and pages, if you need a proof.
