Who were some of the main targets of the red scare?

During the Red Scare, particularly in the early to mid-20th century, main targets included communists, socialists, labor activists, and leftist organizations. Many individuals were accused of being un-American, leading to widespread fear and suspicion, especially during the McCarthy era. Prominent figures in Hollywood, educators, and government employees faced scrutiny and blacklisting, while immigrant communities were often disproportionately targeted. The wave of anti-communist sentiment resulted in numerous arrests and violations of civil liberties.
