Fair points. For my part I date much of this movement to the early 1990s, with the irrational anti-Clinton hatred, the rise of talk radio as a force in generating and sustaining political talking points, and the impact of Newt Gingrich and his grievance-based agenda seeking a constituency. The Tea Party then became the bridge that ultimately passed it along to MAGA, which is leaving its own imprint, and in a particularly destructive manner. My two cents' worth anyway.
