“This would never occur in any other language. ”
Incorrect. At Harvard’s graduation a speech in LAtin is given there are likely fewer Latin speakers than Yiddish speakers today.
I didnt read through the entire thread, SO this may have been mentioned but I a m glad I speak/understand Yiddish it was the language of the Gedolim of a generation ago. We still have numerous recordings of Yiddish speeches by R’ Moshe R’ Yoshe Ber (available on YUtorah) among others. I think being able to hear thier Torah firsthand is worthwhile
