99 years ago, Vice President Calvin Coolidge offered some thoughts on the "enemies of the republic" to the readers of the women's magazine, The Delineator. books.google.com/books?id=AD5RA…
The nation was rife with "disloyal" teachers and bad apple college professors who needed to be exposed. He called upon the nation's patriotic women to undertake that work. 
The nation's campuses were rife with radical left wing ideas that, if taken up by impressionable students, could lead to the destruction of the republic.
Valparaiso was a hotbed of bolshevism apparently. Amazing how Northern Indiana managed to recover from that.
In 1919 Mildred Lewis Rutherford, an activist who had helped arrange for the construction of several Confederate monuments in Georgia, expressed concern that the textbooks white students were reading were all wrong. She encouraged women to create textbook selection committees.
The problem was that the existing textbooks encouraged students to be too critical of America. They emphasized the cruelty of slavery, minimized states' rights, idealized Lincoln's vision for America, and emphasized the cruelty and injustice of slavery. So unpatriotic!
Anyway, for those who think the anxieties about the place of slavery and racism in America's history provoked by the #1619Project are somehow new...they're not. It's a little dispiriting, however, to see some of these early 20th century, reactionary lines of argument reappearing.
For much more on Rutherford and these battles over how children should be taught the nation's history so as to make them good, patriotic citizens...see Chapter 2 of this excellent book. google.com/books/edition/…
