Put another way, some folks are atheists and they raise their children to be atheists. But, some of those people may enjoy matzoh ball soup. They might listen to Klezmer music. They might say "Oy! Enough with the matzoh balls, already!"
Such people would be recognized as Jews (by themselves and by others) even if they didn't care about religion.
Sorry.
I still don’t understand how one can call himself Jewish and yet not have any connection to Judaism except through genetic inheritance or culture.
It still baffles me.
Best regards.
