The Bible warns against false prophets, etc.
And, obviously, anyone who who has a world view they don't share can't be prophesying Truth, so they cannot be representatives of God.
So in their world there is only one thing to call it.
Call it narrow-minded, arrogant, bigoted, etc, etc, etc as much as you want and I will agree. But it is at least a consistent narrow-minded bigoted arrogance.
