It’s as if she’s upset because God who in her mind is above and separate from all religions would discriminate one over another. God is not “arrogantly” picking one over another, actually if you look at them Christianity would probably be His last choice as it is the only one that requires His suffering and death. The truth is that He only represents Himself, is only present in one, that being the “religion” represented in the Bible, name it what you please.
