A Rav went to Rav Shlomo Zalman Auerbach asking for an approbation on his sefer.
Rav Shlomo Zalman Auerbach REFUSED to give the approbation because the Rav had said disrepectful things about Rav Kook.
Rav Chaim Sonnenfeld also refused to give approbations to someone who had said disrectful things about Rav Kook.
I am surprised the Mods allowed such lack of Kavod to Rav Kook, I dont think such a similar statement would have been allowed for any other Rav.
