GAW, I disagree that children from “stronger” homes will be able to hack it. I know people whose kids are in special programs in public and private schools, in more self-contained rooms even so not subject to the general atmosphere and it still kills them.
Where did I just read this story…of a (I think frum) Holocaust survivor (nebech, can’t judge) who decided to send his teenage son to a college in the Bible belt to give him the opportunity to stay strong among the goyim, as he himself had had to do as a young man. Disastrous.
