Not exactly great "Mormon propaganda" since the main character is extremely neurotic from being raised in a homophobic religion. It's less than a glowing endorsement of the religion. It's not like this was commissioned by the Mormon church to convert gay furries. It's written by a gay guy.
Accusing this other guy of gaslighting/lying because he disagrees with your reading is absurdly immature. I genuinely can't imagine how you came away with any of the opinions you posted here besides just going into it expecting it to be cynical and then ignoring anything that counters that idea.
