Answer:
The platform used by the second Ku Klux Klan was the spread of protestant beliefs. Members of this phase of the Ku Klux Klan engaged in promoting these beliefs through anti-black, xenophobic, anti-semitic and anti-catholic activities.
Step-by-step explanation:
The second phase of Klan began as early as 1915, when a movie called The Birth of a Nation was released. This film presented a heroic image of the Klan and, therefore, is considered responsible for the rebirth of the organization. This phase of the Klan extended until the mid-1940s and was the period of greatest strength of the Ku Klux Klan.
At that stage, Klan had approximately four million members spread throughout the United States. Throughout the 1920s, members of the Klan began to make public appearances, gained influence in politics in certain places, and added to their ideology xenophobia, anti-Semitism, and anti-Catholicism.
