Mammele -“Health: There’s no way only frum people will get custody. Too many BTs with non frum families involved.”
No one can force anyone to have custody!
Usually it’s a fight between parents. Your assumption that only Frei people will take them is false! Governments have a hard time getting anybody to take them! Because it costs a lot of money to raise children and who wants to do it when it’s s/o else’s kids?!?
So once the government removes the kids, the Frumme can offer taking them in!
