Let us account for all we see by the facts we know. If there are things for which we cannot account, let us wait for light. To account for anything by supernatural agencies is, in fact to say that we do not know. Theology is not what we know about God, but what we do not know about Nature.
Unless a person can give reasons, there is, literally, no reason why anyone else should take that person seriously. But without reasons, all we are left with is emotional blackmail. We sometimes call it 'moral blackmail,' but it has nothing to do with morals, only with the implied juvenile threat of having a tantrum unless everyone else gives in.
