No, it isn't true. Archbishop (and later Cardinal) Stepinac was never present at any "forced conversions".
Furthermore, Cardinal Stepinac will probably end up inducted into Yad Vashem as well.
"There is no doubt that one day the Croatian Archbishop (later the Cardinal) Alojzije Stepinac (1898-1960) will be included into this list. An official request to the Israeli Yad Vashem for the posthumous inclusion of dr Alojzije Stepinac to the list of Righteous has been sent by dr Amiel Shomrony and dr Igor Primorac, now both citizens of Israel. The request has been sent twice, for the first time in 1970, and then in 1994, and both times refused. Bear in mind that only saved Jews and their descendants have the right to nominate candidates to Yad Vashem. Official Jewish organization in Croatia did not send such a request yet.
According to solidly based data he saved several hundred Jews during the WW2: either by direct action, or by secret rescripts to the clergymen, including mixed marriages, conversion to Catholicism, as did some Righteous in other European countries (in Greece for instance).
