CR10 – you wrote, “2. That yeshivish Askenazim be more open-minded and inclusive of other yeshivish people of different cultures.”
I don’t know why that is, but I’ve noticed that too. Sephardim are much more comfortable amongst Askenazim (I.E. Shuls and Yeshivas) than Askenazim are amongst Sephardim (Shuls and Yeshivas).
Sorry, I can’t explain it! Maybe someone else knows why. 😐
