Just so you know, LGBT+ people who are also religious are caught in the middle. If they don’t abandon their attractions, they get criticism from some well-meaning church people. If they don’t disavow their faith, they get criticism from some well-meaning LGBT+ people.
If you’re an “ally” or an “advocate,” accept people as they are. Believing or unbelieving. In or out of the closet. In or out of the church. In or out of the pride parade. Advocate for the whole individual person: weird beliefs, messy contradictions and all. Because being an ally is just about deeply caring that another person is OK. Not about waving a banner for an exclusive group.
