Yeah I'm sorry, but this is a non starter. Don't patronize me by dismissing my claims as 'opinions and feelings'. Ed Greenwood is not 'some developer on twitter'. I cited the Time of Troubles and the Silence of Lolth as specific events in FR history in which the source of divine power and the consequences for the death or incapacity of deities is clearly laid out. If you don't want to acknowledge that as specific examples, well-established in FR history, then we don't really have anything to talk about. You yourself still can't find a specific passage that explicitly spells out that deities in FR are completely optional or else you would have cited it yourself, but expect me to throw away decades of lore established through the novels, video games, sourcebooks, and writings of the man who made the setting to take on this assumption of yours that contradicts them? Not a chance.
