“But your concern about RBS is real- there are enough Anglos here, and infrastructure (English-only shuls, American style schools and summer camps) that one can live comfortably without ever really integrating into Israeli society. One has to make a conscious effort to integrate.”
But if you do want to, you can.
“Beitar is more Israeli, with an Anglo presence, have some chasidish elements as well (especially in B, although probably fewer Anglos there) but I am not sure how comfortable you will feel there as a working chareidi.”
I had the same thoughts about Beitar. It might be worth looking into, but I was concerned that it might be too “right-wing” for you.
