shlishi,
1) Extremely few Chareidim know of that apikorus/rasha organization that tries to convert Jews away from Judaism. (The one that is being discussed here unnamed.)
This organization has hundreds of members, 95% of them are ex-Hasids (extremely few?) who are hateful and angry, many of which feeling they are being denied the help they need to achieve careerwise, because of ideological differences. (If you seek a career, you are a GOY in those communities). So they leave their communities and toss all Frumkeit.
2) Chareidim not only admit there is a problem, but have many many extensive organizations to combat OTD. What are the MO doing about their much larger problem with it and what MO organizations combat OTD and and try to bring their brethren back into the fold?
The need for a Mod Orth organization doesnt negate the need for a Chareidi organization to interest these ex-Chareidi kids who are going to that despicable organization and leaving all Frumkeit behind.
Charedis might have many organizationss, but none that are offering educational/career opportunities, in addition to extra-curricular activities to keep these kids happy, interested and busy with religious influence.
