Well, I guess we can see what an understanding, open-minded person you are. The news that they're not "real" Christians will be welcomed by the world's Catholic millions who hang on your every word.
Perhaps we should refer to their sect as the “No True Scotsman” Christians.
Christianity is not understanding of teachings counter to the Bible. Evolution is false, and homosexuality, lying, adultery are sins. I know that seems harsh, but that is what Gods Word says (OT and NT for you word-splitters out there).
