You're free to have your own feelings on the matter, but you're not disagreeing with me - I'm just explaining how the rules and the lore current works in 5e; it's factual to the current 5e lore. Open and shut. Other threads have discussed this at great length, and I'd recommend you take a look in at those so we don't repeat ourselves ad nauseum. You can say you don't like the rules and lore as written, and that you don't think that the 5e lore for the realms post second sundering makes sense to your sensibilities - but you're disagreeing with the system and the lore itself when you say that. The way things work in the realms literally changed after the second sundering, and they work differently now - one of those differences is that the deities are more hands off and they channel their power, and the power of their folios in many more subtle ways. That's just how it is currently.
It's okay to have in your mind, personally, what you think a certain thing 'should' be - and you can even play that way at your table - but if the folks who write the lore write about the way it changes, and you don't want to acknowledge that or move with it, they aren't the ones who are 'wrong' or 'going mad' - you're just going off book because it makes yo happier to disregard the lore and adopt your own. That's fine, it's great, but you're not in a position to act like your definitions are meaningful to anyone but you, or that they are 'proper' or 'correct' - they're not. If you don't like the present day lore and how it's spun, you don't need to use or engage with it, but you can't expect the world to follow you in that - it's your choice, and yours alone. The lore, as you posit, is not, in fact, on your side here - not in the present day realms of 5e, post second sundering.
Like I said, go have a look at the other threads about this - the discussion goes into great detail about the changes, how they work, and how the lore works now; it makes a lot more sense than you're giving it credit for, but anything I say to that tune here and now would just be repeating a discussion that has already happened in great depth elsewhere on the forums.
