In your first “FACT” you end off “Most intermarried.”
Is this referring to the line preceding it i.e. that ” most [of] …thier children, grandchildren and great-grandchildren” intermarried or the opening ” Most frum Jews who left Europe.. intermarried.”
Either way Im curious as to your source. while Sadly most recent data indicates an intermarriage rate of 58% which can be characterized as “most” as recently aS 1990 it was “only” at 40% which is obviously not “most”
(i’ll grant that this number includes many Jews who arrived (or ancestors did) mmore recently) But I find it surprisng that “most children ” of those who arrived, let alone they themselves intermarried.
