"The story of Coughlin, the demagogic radio priest who dominated American airwaves during the Great Depression, offers an intriguing analog-age precedent to the digital-age debates over the limits of free expression." https://slate.com/technology/2021/01/father-coughlin-deplatforming-radio-social-media.html
@estherschindler It is a good read. I feel I should mention Coughlin wasn't the only Trump predecessor from the 30s. Huey Long was, if anything, an even more direct ancestor. For more on him see his bio by T. Harry Williams and the brilliant novel All The King's Men based on his life and times by Robert Penn Warren.
