I'm usually on board with you, but here I think you're kind of shouting into the wind. The people who label GSRM folks "sinners" are not the kind of people who are going to care about hurting said folks. They WANT to hurt them.

Christianity is a lovely idea, I suppose, though it's very unoriginal, but it's not worth it to argue with people who say they're Christians but deal in hate (which is unfortunately the vocal majority).
