Avi K,
My perspective on these threads: For many Ashkenazim, especially Chassidim, Yiddish is regarded as an important element of their culture. And your derision of Yiddish and other Ashkenazic practices in favor of Israeli or Sefardic ones is perceived as an attack on that culture.
If your problem is that some people conflate Ashkenazic/Chassidic culture with Judaism as a whole, thus perceiving other Jewish cultures as “less than”, I agree 100% that this should be opposed. But that is not how you are coming across. You seem to be going to the opposite extreme – trying to paint Ashkenazim as “less than” via your Chacham Ovadia ZT”L quotations, calling Yiddish insulting names, etc.
You seem to have a great desire to see the Jewish people as a whole come back to Eretz Yisroel. But if someone feels that his dialect will be mocked, that his choice of headwear will inspire hatred, and his family customs despised in Israel, isn’t that counter-productive to your goal? I understand that you have been made to feel the same way, but do two wrongs make a right?
As a side point – it’s clear from reading Shoftim that the Jewish shevatim spoke with different dialects even before the first Beis Hamikdash was built!
