“I know many in the Charedi world would throw him out.”
Do you really?
First of all – until a person is R”L in such a situation they have no idea how they themselves would react so I doubt that anyone could know how somebody else would react.
Secondly – I know an awful lot of Chareidim and if I had to bet, the vast vast majority would “stick by their child” and not “throw him out”.
