Let's put it this way:two Jews are lying on the floor in immediate danger of life,a Jewish ambulance arrives(made up of a crew educated in jewish law)but they can carry away only one of the two senseless dying Jews.If the id of one of them says he is called for instance Joseph ben Avraham avinu(our father),the crew will let him die in order to save the other one,who is a born Jew.So,converts are still viewed as inferior to born Jews.
