Did your family speak Yiddish in the past? Are you ashamed of being an Ashkenazi? Are yuou preferring the Israeli Hebrew “Shabat Shalom” (with its not quite Sefardi accent), rather than the Yiddish “Gut Shabbos” because it reflect your political views.
On a related question, if you are from Boston, do you make an effort to drop a medial “r” or not to drop it. If you are from Brooklyn, do you speak “Brooklynese” or do you make an effort to sound like you were taught proper WASP pronounciation? If you are a Brit, do you make an effort to speak “RP”. IF you think this paragraph is ridiculous, so is the question on whether to prefer a “Sabbath greeting” in Israeli Hebrew or Yiddish.
