Step-by-step explanation:
A. Most Klan members were Protestants.
The Ku Klux Klan, during the 1920s, predominantly consisted of members who were Protestants. They held deep-seated anti-Catholic sentiments based on religious differences. The Klan saw Catholicism as a threat to their Protestant values, and they believed that Catholics posed a danger to the social and cultural fabric of American society. As a result, they supported anti-Catholic legislation in an attempt to limit the influence and power of Catholics in the United States.
