I'm an Atheist, but just because I don't believe in deities, doesn't mean I think that gays are normal in their sexual proclivity. That said, I'm not in favor of killing, harming or imprisoning them, as they do in Islamic nations. It's just an abnormal part of society that is none of our business. If there is a deity, it's for him/her/it to determine which direction they go after death, not people.
Mormonism is just another example of the three worst religions on the planet, the Abrahamic ones, with Islam being the most vile of the three.
