Being a Jew is defined by birth.
Being Jew-ish is defined by behavior.
Three generations of not being Jew-ish usually results in a Christian.
So much for being an atheist or agnostic.
lol so they become reformed Jews instead of Orthodox. And you think that is bad. lol
The vast majority of Jews became Christians a long long time ago, beginning with the rabbi Jesus reformist ministry in Galilee, and long before Constantine. They're the vast majority of Zionist Jews, have been for going on two millienia. Just because this doesn't sit well with the racists isn't a cause for alarm and the destructive self-segregation typical of those unreformed Jews and their weird neurotic obsessions with their genealogies, many of which were faked a long time ago as well. They're more Jewish as a result than the average Chasidic is.
Jewish tribal genes are spread all over the place around the world. That's because most moved on, knowing being 'The Chosen' had nothing to do with genealogy, race, or priesthoods, it had to do with grace and working to fulfill the Covenants, old and new.
