@yankel-berel:
As many gedolim wrote, Rabbi Kook wrote and spread heresy in Klal Yisrael, which continues to be spread today by his students and students of his students. Period. This is indisputable as it is simply the facts.
As to your questions, in general:
The Brisker Rav convened the B”D of Brisk for every one of those titles that he felt he needed to use when addressing Rabbi Kook.
Rabbi Kook was mesader kiddushin of the rather young then-bochur Rav Elyashiv, not the nonagenarian gadol Rav Elyashiv. Etc.
As shown above, you can’t bring raayos from stories and/or fairy tales. Stories are very specific in nature and, when quoted, like here, are very much lacking context and other pertinent details.
But the Satmar Rav and Rav Elchonon and others all applied titles to him specifically, titles including “mechabel biKerem Hashem”, “Rasha gamur” and more. Rav Yosef Yedid mockingly called him a Navi (and titled that piece “Regarding an apikoros against whom we must protest”). And that’s besides the others who condemned his Torah, like the Gerrer Rebbe who ruled that Rabbi Kook was “omer al tamei tahor” (and that was after Rabbi Kook supposedly retracted his “controversial” positions – but afterwards essentially rescinded that retraction), etc.
Those are not stories about things that happened, which could have all sorts of reasons that make them irrelevant to anything, like what you quoted; rather, the above are criticisms of Rabbi Kook himself. Just open up a Kovetz Maamarim, for example.
