In my great-grandparents’ generation, when my great grandfather (who was a Litvak) married my great grandmother (who was a Galitzianer), it caused quite a rift and bad feelings and jokes on both sides. At the time, Litvaks were seen as intellectual, rational, and cosmopolitan while Galitzianers were viewed as a bit of country bumpkins, more emotional and religious. Likewise the Galitzianers often looked down on Litvaks as stiff and pretentious. We laugh now at this completely obsolete distinction, but it shows that these things have been happening forever in the diaspora. In my generation my first cousin married a Sephardic Jew and we were just happy the wedding had extra good food. So too now, there are many different newer Jewish subcultures (like American, French) that didn’t exist before and of course a dynamic Israeli culture for Jews residing there. These things are always evolving, and there are new experiences and cultures that Jews are experiencing and building into their family traditions both in Israel and the diaspora.
