So I'm kind of late to the part on this thread. But my two cents.
On the one hand, I feel some validation in being a member of the Orthodox denomination. In my community, we can clearly see the the numbers. In a particular area where the families are a bit older, there is not a single building that doesn't have at least one kid who stops being religious. On the other hand, coming from families of 8++, that's not exactly an avalanche.
Still, all that being said, we are not just a people, we're a family. Who here hasn't played Jewish Geography with every new Jew that you met? To see numbers like these, of generations of Jews that will never be born, of children that may never even know what it means to be Jewish. Whatever our differences, even if its not a brother, but a cousin, it still hurts to see them leave the family. And in so many of the cases its only because they never had the opportunity/took the time to study about where they came from.
