Dear Avira,
Rav Kook was as great as they come. The gedolim of his days considered him on par with the gedolim of a hundred years before. Some try to justify that they are just against his ‘theories’ or ‘policies’. He didn’t have anything like that. Rav Kook doesn’t ever write about how do this or approach that. His whole being was to do what was right in the moment. He exuded Torah even in the most Anti Torah settings. Everything he ever thought about in his life, was nullified to the Torah within him. There is a some sichas chullin in his writings. For those that learn his Torah on everything else, it is not Bittul Torah to read his poems and views of history.
The objections that Rav Kook encountered between the wars, was about how to deal with the issues of the day. The leaders believed Rav Kook was too trusting of the secular Jews to keep their agreements. The Chareidim wanted to hold the line as much as they could and Rav Kook didn’t seem to care for that. In hindsight, the Chareidi leaders never had a chance to hold that line for long.
But to personally attack Rav Kook? To doubt his stature? The Rabbanim of Yerushalayim put ayidden in cherem for that. In the Lita a Rav spoke out against Rav Kook and some of the Gedolim refused to speak with that rav again.
I know all the fables you know and almost all of them are not at all true.
