When someone tells you "Jews do not proselytize" that is a talking point that they were taught to say exactly word for word by Jews or by other Jews

It is a thing the cult members and people given talking points by a institution that they want the approval of do

For example all the people registered to get a certification to teach such and such by such & such will use the exact same phrase word for word that their organization told them

At least this is what I have observed in my opinion
