Do you all realize that no one here has defined the meaning of “holy”, so everyone here is discussing a different question? From a halchic standpoint, it has been quite obviously shown that Yiddish is a lashon chol with no kedusha. Does Yiddish deserve respect as a time-hallowed, exclusively Jewish language, which can connect Ashkenazi Jews to their European heritage? I think only those with an anti-Yiddish agenda would deny that.
