Answer: Members believed that immigrants were superior to native-born Americans.
Step-by-step explanation:
The Know-Nothing Party was created as an anti-Catholic, anti-immigrant, and very xenophobic movement. They believed that native-born Americans were superior to immigrants and sought to limit immigration or ban it outright. The Party members were primarily Protestants who feared that their way of life and traditions would be stamped out by Catholic priests and the new Catholic immigrants coming from Europe.
