The real question is, what did r’ shteinman really say to the yidden in france and is that messsage the same one he would tell yidden in england, or belgium or uruguay.
It IS worthwhile to understand what R’ Nehurai is saying, especially since we know that R’ Nehurai is R’ Meir and on the very same daf (kiddushin peh bes amud bes)R’ Meir seems to contradict R’ Nehurai.
