There is a diversity of Christian denominations and some are (socially) progressive. But we seldom hear about them as angry evangelical ones scream mich louder. But they are there, doing their work as they always have making little news unless you look for it.
For example the Metropolitan Community Church has ordained LGBT clergy since 1968 and United Church of Christ since -72. So there are very socially progressive denominations out there, just wish their voices were heard louder. Or that media reported on them more.
Thinking of it I would like more Christian schisms to be prevalent.
