Observe that there are several groups of identified Jews.
Various orthodox and ultra orthodox sects that believe and attempt to follow the law; and "reform" or "ethnic" Jews who may well understand the Word but who believe God is not involved. And the reaction of the various orthodox groups may not be the same either--the Hassidim object to the nation of Israel on the grounds that it should not exist until Messiah comes.
Your saying there are some so extreme as to not come to see the Ark of the Covenent if it were found?
