Philosopher; as someone who has placee children in kiruv yeshivos, I can say that they are careful to only take verified Jewish children…to a fault. I say this because many parents who are proud of their jewish identity despise being interrogated and forced to provide evidence of their yahadus. They already think that the frum don’t consider them Jewish…lehavdil, imagine the umbrage we would have if someone wanted us to prove who we were… This insensitive attitude I’m sure has resulted in many lives lost. One may wonder; if one jewish child will be deprived of Torah, isn’t it worth the wasted resources on a few others who are not actually yidden?
This has been a gripe of mine for quite some time.
Like I said above, the chazon ish supported kiruv in eretz yisroel. Gedolei yisroel such as rav pam, the novominsker rebbe, rev yaakov, and many others, oversaw kiruv yeshivos in America – rav pam started shuvu in eretz yisroel. Kiruv is far from limited to Aish and “kiruv professionals”, it has the backing of the full gamut kf gedolei yisroel. The satmar rov famously held a shitah that is somewhat similar to philosopher; we need to be sure that our own are taken care of fully before branching out….he did however, say that in post war America, where people barely could keep shabbos and kashrus without great mesirus nefesh.
Would he say it in our time? That’s anyone’s guess…i personally think he wouldn’t.
