Why is the world so into making the non frum frum, and not so concerned of keeping the frum frum.
That question is based on a false premise.
“The world” is quite concerned about keeping people frum. What do you think chinuch habonim is all about? What a slap in the face it must be for a parent to hear that they are not so concerned with keeping their children frum when they invest their entire lives – emotionally, physically, spiritually, and financially – into raising their children to be ehrliche Yidden!
What do you think yeshivos and Bais Yaakovs are all about? What a slap in the face it must be for yeshiva and Bais Yaakov administrators, rebbeim, moros, and even donors to be told that they are not so concerned with keeping talmidim and talmidos frum!
And they’re not even satisfied with their children and talmidim remaining frum; they are moser nefesh to instill a proper chinuch, on the highest possible level, to help them grow into real yorei shomayim. And they should be accused chas v’shalom of being “not so concerned?!
