I can’t quite put into words what I’m thinking so it won’t be as eloquent as some of you, but it’s not that I think Mariah is “pretending to be gay” per se. What I mean is in her mind, she probably thinks she is. I know she thinks she’s this super-woke intellectual who has all the answers to the world’s problems, but in actuality she’s still very young, very immature and has very little life and real world experience. I too do not believe she ever felt that she fit in among her siblings, which I feel is pretty evident in some of the things we’ve seen on the show. I also don’t think she ever truly believed in her church’s teachings. She just said the “right” things to make her look like the golden child in Kody’s eyes. (I might add that with children, it’s very important that they develop their own personal faith apart from their parents once they are older. Most of us want our children to believe as we do, but I don’t want mine to just believe because I believe. I want it to be personal to them. If not, it won’t take much for them to fall away from faith. They’re just towing the line, and the moment doubt comes, faith is out the door). But I digress.
Anyway I think she made friends with and latched on to the identity of those who befriended her. The irony is she thinks being this LGBT outlier has made her intellectually superior to everyone else, but really - with no depth to her own faith - she was an easy target for the first group who would make her feel the acceptance she was craving.
