Answer 1

Roman Catholics and Protestants persecuted them.

Both Catholic authorities and mainstream Protestant reformers (e.g., Luther, Zwingli) rejected the Anabaptists as dangerous radicals—opposing adult-only baptism, separation of church and state, and other practices—and took harsh measures (imprisonment, fines, execution); events like the Münster Rebellion intensified the repression.
