How did the red scare and McCarthyism affect civil rights?

The Red Scare and McCarthyism significantly impacted civil rights by fostering an atmosphere of fear and suspicion that stifled dissent and marginalized various groups, including civil rights activists. Many individuals were blacklisted or persecuted for their political beliefs, often conflating leftist ideologies with disloyalty. This climate hindered the progress of civil rights movements, as activists were often targeted for their associations or perceived radicalism, which diverted attention from racial injustices. Ultimately, the oppressive tactics of this era underscored the need for civil liberties and protections, influencing later civil rights advocacy.
