I think so. The movie is *not* about anything even remotely related to glbtq stuff. But I think it can help us gain a heart for those who do struggle with SSA. I strongly oppose gay activism, FWIW, but do feel for those who experience same-sex attraction.
I guess as Tolkien used to say, good art about the human condition will have applicability to many situations.
If a story about love, can give people comfort and solace it seems like a good thing to me.
