DaMoshe,
It is true that “these people” have a terrible Nisayon. It is true that they require sensitive guidance. It is true that the individual should not be chased away from our community, provided that he has committed to maintaining the standards of Torah. It is true that everybody has difficulty living up to the Torah’s demands, one way or another (more often, it’s actually one way and another). These truths were recognized and discussed by no less “Chareidi” a Rabbi than Rav Elya Svei, approximately twenty years ago.
It is not true that a group of people wishing to whitewash their inability to overcome a terrible test have license to usurp the institutions of the Torah in order to gut the Torah itself of any meaning. It is not true that an apparently observant man can assume the title of Rabbi in order to sanction the systematic disposal of Torah values.
The assertion that, “Since I – who am admittedly prone to doing Aveiros – received an Aliya in Shul last week, it is acceptable to support an anti-Shul whose mission statement is the emasculation of the Torah,” is an outrageous perversion of the Torah.
These distinctions are voiced most cogently by Rav Shamshon Raphael Hirsch ZT”L in his essay “Outrage in Hamburg” (Collected Writings volume IX).
The notion that it would be acceptable for purposes of Kiruv to take this position would be laughable if it wasn’t so appallingly contrary to the Halacha. Normative Halacha prohibits even inviting irreligious Jews to a Shabbos meal if their attendance would require Chillul Shabbos; how, then, can we condone taking this position, whose raison d’etre is לטהר את השרץ?
