Hard to "discuss" a movie with folks who haven't seen it, and are therefore basing their opinions on what they've "heard" or "think" it's about.
Actually, the movie is very much so about the price one pays for being different in society. In this case, it was two gay men. It could just as easily have been a mixed race couple, two women, a mixed ethnicity couple, a widow who has to take a "traditionally male" job in order to support her family, a male who takes a "traditionally female" job. It was far less about homosexuality as it was about intolerance, the ignorance of certain people who fear what they don't know and therefore criminalize it or make it a "sin"and the price those ignoirant people make other pay because of their ignorance.
BTW, the God I believe in loves everybody, regardless of their sin. And I think He hates the sins of superiority and judgementalness most of all.
