I hear what you were saying about there not being other Machlokesim to this extent, but I’m not sure if that’s true. The Vilna Gaon called the Chassidim Baal prophets and held they were Mamash Kofrim. The Brisker Rav supposedly said about Rav Chaim Shmulevitz that his wine is Yayin Nesech after the latters statement about the soldiers (i don’t know how serious he was).
in regards to Rav Kook talking poetically, I hear your point, but I think there are other Gedolim who did the same. Chazal express themselves poetically in Aggaditah. Rav Tzadok and other Rebbes do.
I hear your points though and will consider them.
