Haimy where exactly to you get your facts from?
Or your just interested in hate.
Why is your question to Chabad a not all kiruv organizations?
I work in the teen program and each teen that comes to the shabbaton, was in the teen program for at least a year, and no rabbi is interested in putting so much effort in a goiy, and any time we a approach someone for tefillin, we ask if his mothers mother was Jewish, and before we marry them the rabbonim do a thorough research in there yichus, check their grandparents kvura, and many other things.
One of the rules chabad has is, that we won’t even “bar mitzvah” someone that his not Jewish, or someone that didn’t have an Orthodox conversion, because that might lead to a different rabbi marring him off, and using some “rayeh” that he had a orthodox rabbi by his bar mitzvah, (even though it’s not a rayeh.)
Every chabad house rabbi knows exactly who is Jews and who is not in his Chabad house, no one is interested in putting thousands of dollars into someone to grew in his Judaism, if he is not Jewish.
On side note I know of a shliach that didn’t accept $200,000 at least, from someone to build his Chabad house, because he was not Jewish and he wanted his name on the building.
So get your facts straight.
