Why did nativist dislike the bew immigrants?

Nativists disliked the new immigrants primarily due to cultural and economic concerns. They perceived these immigrants, often from Southern and Eastern Europe, as a threat to American values and social cohesion, fearing that their different customs and languages would undermine traditional American society. Additionally, nativists believed that immigrants took jobs away from native-born citizens and contributed to social problems, leading to increased competition for resources and employment. This blend of cultural anxiety and economic fear fostered a hostile environment towards immigrant communities.
