Yabia wtvr, Hebrew!?! Are you kidding???? I’ll bet LESS people in the USA can follow a drusha in Hebrew then in Yiddish.
Since the OP asked about Yiddish, let me tell you a 100% emes story from the last siyum. When the Klozenberger Rebbe was speaking in YIDDISH, I was standing near the 50 Yard line taking to the person who ran the Meadowlands Sports Complex and the person who oversaw MetLife Stadium. The gentleman from the Meadowlands looked at me and said, “I don’t know what he’s saying but one thing I do know from good speech. He is very very passionate.”
If the goy could “הער” and “דעהער” it in Yiddish so could you for a few minutes.
