1. There were no Jews in Massachusettes. It was officially Judenrein until the revolution (as were most of the American colonies). The only New England colony that tolerated religious minorities was Rhode Island, and toleration did not include full civil rights, merely not being kicked out.
2. Pre-holocaust immigrants were not seeking religious freedom. In all fairness, the Europeans we lived under weren’t objecting to putting on tefillin or keeping Shabbos. Economic and political freedom was the issue in that period. Immigrants from the Soviet Union pre-WWII largely had a religious motivation, but there weren’t many of them. Post-war hareidi immigrants were often motivated by a desire for religious freedom since many perceived that as lacking is Medinat Yisrael.
