Why the Palmer raids targeted immigrants?

The Palmer Raids, conducted in 1919-1920, targeted immigrants primarily due to the widespread fear of radical political movements, particularly communism and anarchism, following World War I. Many immigrants were associated with labor strikes and leftist ideologies, which heightened public anxiety about potential subversive activities. Additionally, the raids were fueled by a broader nativist sentiment that viewed immigrants as threats to American values and societal stability. This combination of fear and prejudice led to the aggressive crackdown on immigrant communities during this period.
