I don’t think they are doing this to annoy anybody. I think they are people, like you and me, struggling with stuff. I think they have been in denial about what they really are for a long time.
I know a thing or two about denial. My great grandmother was an Indian, yes, we use that term more often than not, and me, and my siblings are the first ones in my family being open about it. It wasn’t a walk in the park coming out, but now even my folks are proud of that part of the family.
I feel sorry for LBGT people. I wish I could help them, and they are in my prayers.
