Note however that Paul the Apostle spent considerable effort to teach his non-Jewish followers to respect Jews and their faith practices, see especially Romans 9 thru 11 inclusive (which include the information that God has never abandoned His Jewish People, notwithstanding all their historical shortcomings, and that all of them will be saved.
How much a misunderstanding or misreading of Paul may have contributed to anti- Semitism in years past, is discussable, but it really doesn’t appear very accurate to lay the blame on Paul himself.
“and that all of them will be saved.”
Disagree...only if they have accepted Jesus as Messiah and are born again.
Many have not, and many will not.
