Sorry, but I just don't buy it. We've fought countless wars throughout our past with surprising frequency. It diminished in Europe as they consolidated from a loose collection of warring states to nation states with foreign policies and alliances (not to mention the printing press). The only big change was in the brutality of war as the participants changed from a professional army to a conscripted army starting with the French revolution, but that has little to do with the ease of expressing ideas (unless you count the spreading of the idea of a conscripted army). Since that time, the frequency of wars has steadily decreased, especially after the Vietnam war (due to the dissemination of inconvenient information). People have listened to far-left and far-right broadcasts ever since broadcasting became a thing. Internet echo chambers are nothing new. Before that it was pamphlets and newspapers, and before that, street criers and public houses. The world is steadily becoming a safer place. The only difference is that as we become safer, our perception of "safety" becomes further and further warped. Things that would have been shrugged off even 50 years ago are looked upon with horror and fear today.
