Not Vatican II. The Lateran Council. The two biggest opponents to it were Francis of Assisi and Dominic Guzman. They pleaded with the Cardinals until it was agreed that preachers woudl preach, but not proselytize. They would still go out and deliver sermons, retreat talks, answer questions, live out the faith in the presence of all so as to bring the message of Christ. But they would not threaten, coerce or frighten people into acceptig the faith.
Over the years this was forgotten, mostly due to the Protestant Reformation, when all those heated debates between theologians took place. The Jesuits started to proselytize again using scare tactics to conver the Indians in the Americas. The Franciscans and Dominicans, faithful to their founders, filed a formal complaint against the Jesuits, one in civil court and the other in ecclesiastical court. The Jesuits lost in both courts. The Franciscans and Dominicans argued that faith that accepted our of fear rather than love is not faith. They also argued that the mission of the Dominicans and Franciscans was to preach the faith with charity and that the Jesuits were sabbotaging it, because they were forcing the natives to be baptized. The third complaint filed by the Franciscans was that they had been founded to convert Catholics, but the Jesuits were allowing Catholics to live laxed lives, while they bullied the Indians to comply with Catholicism and were engaging the help of the civil athorities, which was lay and Catholic. It was a big mess and took years to fix.
To this day the Franciscan, Junipero Serra and the Dominican Bartolome de las Casas are revered by the Hispanic Americans, because they protected their religious freedom way back in the 1500s. Yet, despite not proselytizing, the Franciscans did manage to convert the Catholics to Catholicism and the Dominicans managed to convert the Indians, because they were dearly loved. Later, Isaac Jogues, SJ would come as a different kind of missionary and made converts. Francis Xavier did too in the East. Once the Jesuits toned it down, they made great progress in converting people. It was not just people paying lip service to Catholicism.
The three orders: Jesuits, Dominicans and Franciscans have very good relations with people of other faiths for their kindness, compassion and their faith.
Fraternally,
