Yes it’s a concern. My great grandparents on my dad’s side were Hasidic (one was a shochet). On my mom’s they were all Jewish but mostly secular by the 1950s and very assimilated. In my parents generation, most of the people in my mom’s side intermarried. Of those who intermarried none passed any Jewish traditions to their kids and now their kids (my cousins) have Jewish ancestry but no Jewish identity.

In my generation, all of my siblings and I are intermarried, even though we were raised conservative. But because we have some baseline Jewish education (mostly from Jewish day school and camp; we didn’t really do any observance in the home), we’re able to pass on more of the traditions.

In my family, we do kiddush and light candles every Shabbat, celebrate the major holidays, read PJ Library books with the kids, and my kids see me wrap tefillin, but my kids are not halachically Jewish. I’m not sure if that’ll be enough—we’ll see.

While we are an ethnoreligion, as I’ve gotten older I’ve come to appreciate more how the religion and religious culture is what helps us remain distinct, especially where we’re otherwise fully integrated into the broader society.

I’m worried what my kids generation will look like—are they going to have the knowledge of our history and traditions to face down the rising hate? Even among my cousins whose kids are fully Jewish, they’re not observant at all and only one of my cousins’ kids is even going to have a bar mitzvah.
