Reply To: Chabad? Most non religious Jews are not halachikly Jewish.

The Godol Hador was asked this question, if tgere is a need to do what Ezra did by identifying yichus of everyone (see Perelman Asara Yuchsin)? He answered that Ezra did not do it while the Yidden were in Bavel. Only when they were immigrating to Eretz Yisroel – only then did Ezra do so. You see, the problems we have of our Nation being contaminated by goyim or mamzerim is an ancient problem that yidden had even after a mere 70 years of golus Bavel. Yet while in golus Bavel kiruv was done, brissim were made and Rabbonim were messader kiddushin without concern of brocha lvatalah. Think about it.
