Evalimoshavlo:
Once prophecy ended in Tanach, it was later given only to children and fools. Given that you are clearly claiming to be revealing a prophecy (because there is no rational way you could claim such a thing), and your writing seems to indicate that you are not a child…
anonymous Jew:
Can we stop believing that which the Torah and our sages tell us? A heretic could do that, but a believing Jew cannot and, if they have any brains, would not. Of course the Torah protects. There are answers to your questions as to what happened in those cases, including midas haDin being a different calculus than in normal times, etc. But what makes you claim there was “no assimilation” in all of those? There certainly was assimilation in at least some of those including (to some extent) even in Egypt, the first galus.
