I am planning on putting together the most unsettling doubts in a big letter, like Noah's Ark, inconsistencies in the gospels and unfulfilled prophecies and sending that to my dad. If he has half a brain left he will at least reply that some things are not clear yet.
This will feel good, but will not sway any elder and will guarantee your df'ing.
Just CHILL. Keep your doubts to yourself, post here, read read read.
Don't talk about your doubts to elders and expect them to understand. They won't. To them you are a threat, and have been reached by Satan.
