A person I know always jokes as if he knows better than God, may God protect us, and speaks disrespectfully about the divine essence. He jokes about knowing more than the leader and belittles him as a reference and leader. I know he is joking and does not mean what he says, especially when angry, but I cannot accept this behavior. I always tell him to stop, but the others around me say he is just joking and that it's normal; he doesn't mean it.
