Yep. They were called “rebaptizers” during the Reformation by Catholics and pedobaptist Protestants due to baptizing adults who had been baptized as infants. This is because they rejected infant baptism as invalid and therefore not actual baptism. In their eyes, they never “rebaptized” anyone.
I have never taught Anabaptism… But the right baptism of Christ, which is preceded by teaching and oral confession of faith, I teach, and say that infant baptism is a robbery of the right baptism of Christ.
