“I cannot comment on Western European Rabbis as I do not know if I am familiar with any. “
Why do you flaunt your ignorance? You think that the entire frum world is charedim from Eastern Europe. Well, it isn’t. There aren’t any significant Jewish communities in Eastern Europe any more.
“I think it is significant that all three rabbis you bring from Eastern Europe are controversial figures in the eyes of a significant portion of the charedi public.”
Not my problem.
BTW the Rema himself was very learned in secular wisdom although he didn’t himself attend university. And during his lifetime, Jews did attend university (mostly in Italy) and he did not object.
” if you did not hear of R’ Lichtenstien, it is purely because of ignorance. I and many others may not follow his halacha, but much like R’ Kook in his time, he definitely is a gadol. “
R’Lichtenstein is in many ways much more traditional than Rav Kook, particularly in his approach to Zionism.
