Not to mention that the marriage rate between Mizrahi and Ashkenazi Jews in Israel is something insanely high like 25-30%. Having people from diverse backgrounds and blending them into a cohesive society - while overcoming challenges created by differing skin color, culture, language, and economic backgrounds - was far from easy. Israel managed to pull it off, likely in a way that no other country has done before.
Stating that the problems in Israel are the result of racism from Ashkenazi Jews is just straight up ignorance too. The Ashkenazi Jews overwhelmingly vote left, and it's actually the Mizrahi Jews who largely support Netanyahu.
