Nishtdayngesheft,
1. While there are are some talmidim who seem to feel that way that is not the impression that I get from Rabbi Weiss. In fact, when I knew him (albeit thirty years ago) I had the distinct impression that he is much more frum than he lets on.
2. If they called themselves a halfway house no one would come.
2. Rav Asher Weiss says at the end of Minchat Asher on Sefer Bereisheet that today we have to bring people back with chesed as did Avraham Avinu.
3. How dare you make such a statement? How do you know where they have gone?
FYI, Rabbi Weiss explicitly used the term “became so frum”.
