“I think the litvishe and chasidim argue on עת לעשות לה הפרו תורתך, make time when the Torah will be disrupted”
Which “chassidim” are you referring to? And which “Litvaks” are you referring to?
I can quote you from either of the sides the other way around..
The term of Chasid and Misnaged these days are just used as an identification, there are no true original Yesodos differences anymore…
