YO – I’ve known plenty of satmar chasidim, both talmidei chachamim and hamon am. Among the ones who learn a lot, there’s a complicated relationship with litvishe, chaim Berlin included
. They understand that the yeshivos have authentic Torah; the satmar rov was very machshiv people like rav moshe, rav yaakov, and told chasidim to daven by rav yaakov yosef, chief rabbi of new york. They will learn the igros moshe but not pasken out of it
They also will not shy away when the rebbe criticizes litvish people for voting, etc…but they can respect litvishe people on an individual level, and will talk in learning with them(i.e. me) the same as anyone else. They don’t always assume that I’m modern, but there is such an undercurrent.
With the hamon am…many are open, and many are closed off, thinking that anyone who doesn’t follow the satmar rov’s shitos regarding voting etc..are not frum. But that’s not something you see by the lomdei Torah.
