One aspect of that cancer is akin to the loyalty oaths of the 1940s and '50s. Professors were often required to sign statements that affirmed their loyalty to the United States government plus swear they were not members of any organizations, including the Communist Party USA, that sought the overthrow of the United States government. Fortunately, the U.S. Supreme Court struck down loyalty oaths as a condition of employment in 1964.

Today we're seeing the re-emergence of the mentality that gave us loyalty oaths, in the form of mandating that faculty members write "diversity statements," especially as part of hiring and promotion procedures. They are forced to pledge allegiance to the college's diversity agenda. For example, the University of California, San Diego requires that one's "Contributions to Diversity Statement" describe one's "past experience, activities and future plans to advance diversity, equity and inclusion, in alignment with UC San Diego's mission to reflect the diversity of California and to meet the educational needs and interests of its diverse population (http://tinyurl.com/mm6vzzq).
