“I don’t think I should be learning Rav Kook yet since I don’t feel confident that I will be able to filter out the krum parts”
While I am not a talmid of Rav Kook — I identify more with the Religious Zionism of Rav Reines and Rav Soloveitchik — I would never call the writings of an acknowledged gedol of Rav Kook “krum”. That even applies to something that has been unanimously rejected by klal Yisrael such as his position on women voting. (We follow Rav Uziel who disputed Rav Kook on that.)
I’ve also been told by Rav Kook’s talmidim that his writings do not translate well into English, which makes them less accessible to those for whom our first language is English.
