I’m from a Muslim country, and among Muslim Americans same sex relationships are taboo. While Muslim support for same sex marriage crossed the 50% mark a couple of years ago, it’s completely rejected within the community itself. (Almost no Muslim Americans identity as LGBT, and virtually no mosques will perform same sex marriages: https://www.cnn.com/2019/05/28/us/lgbt-muslims-pride-progres....) But the many Muslim Americans who oppose same sex marriage don’t oppose the “existence” of gay people. They believe, consistent with their religion, that marriage is for procreation and government sanction should only be extended to heterosexual relationships. They are also probably ignorant on the issue of sexual orientation being an innate trait. My aunts don’t want to grant government sanction to same-sex relationships, but it’s unfair to say they’re a danger to the “existence” of gay people.
