I wrote a really kind response but left it halfway finished and it was missing when I got back to it. I just want to make a few important points without having to dance around feelings. I'm sorry if it comes of curt, you are an amicable discussion partner and I value gut feelings and novel ideas more than most, but the evidence points in another direction and I must point that out since there are multiple factors in this conspiracy. Those factors are:
1. false propaganda of Vitamin A toxicity in mainstream media,
2. false propaganda of the importance of Vitamin A in mainstream media (A is the single most important vitamin)
3. Vitamin A is also the hardest vitamin to come by, and especially the hardest to procure enough of in modern culture.
4. the war against fat and animal products, (lack of dietary animal fat completely corrupts Vitamin A intake - as well as precursors).
5. the vegan/plant-based/SAD diets destroying Vitamin A intake by the lack of the
most important mineral: zinc (and the high intake of copper which prolongs this issue).
6. that Vitamin A is the single most important nutrient for all body functions and growth, including
sleep/circadian rhythms, fertility, organ formation, bone density, height,
muscle growth, .
7. high dose vitamin A (even from synthetic sources) has been shown as a cure for almost every disease affliction imaginable. Studies show this, yet the media fails to report these studies, focusing only on the 2 anti-scientific toxicity studies.
8. the symptoms of aging (such as auditory issues, muscle and bone degeneration) are the result of chronic Vitamin A depletion
9. almost all birth defects are the result of Vitamin A depletion
Vitamin A toxicity is essentially impossible from natural sources. There's only been 2 deaths recorded and that's from synthetic vitamin A over many months, it is almost impossible (and would be highly uncomfortable) to make it to the levels of vitamin A toxicity by eating whole food. Even seal and polar bear liver, the highest possible concentrations in nature, cannot induce toxicity to the point of harm: the toxicity symptoms are mild, yet easy to notice, and do not leave any lasting damage whatsoever.
"Within a few hours of ingesting several million units of vitamin A from polar bear or seal liver. These symptoms cleared up with discontinuation of the vitamin A rich food. Other than this unusual example, however, only vitamin A from “megavitamin tablets containing vitamin A. . . when taken for a long time” has induced acute toxicity, that is, 100,000 IU synthetic vitamin A per day taken for many months."
Your theory makes sense at first glance, and I can see why you arrived at that conclusion, but it doesn't hold up to the evidence. It must be reconsidered in light of the factual evidence rather than just emotional reasoning. Alternatively, the lack of Vitamin A has lead to uncountable deaths, diseases, and disfigurements worldwide.
I will provide sources for the rest of the claims, whatever interests you. I still don't have as much time as I wish to dedicate to this most important conversation. I apologize for the directness and bluntness of all this, but it is so important.
Thank you for sharing your history of veganism with me. I was a vegan for 3 years in my teen/young adulthood, and it did so much damage, much of it permenant. But some of it was reparable with 3 years of carnivore. You would be interested to know the history of India prior to vegetarianism. India was unconquerable when they ate red meat. I can't find this source using google/bing now as the internet has been scrubbed, but in 2017 I remember reading a history which detailed a leader implemented vegetarianism in India in order to invade, and after a decade or two they were able to walk in and take over without a single fight.
