It's very hard to be 13. I believe this father would do better to leave his daughter alone about this and just try to be there for her. It seems to me that he is doing exactly what he wants her not to do. He won't be tolerant of her beliefs, but he asks her to be tolerant of his. I feel for her. She ought to be allowed to freely express her beliefs, and if he disagrees, he can express it midly. She's unlikely to stop being a Christian becuase he berates her; that will only alienate their relationship. She is almost to the time in her life when she can sever her relationship with him. If he doesn't want that, he had better give a little.
