Here is an earnest attempt to explain messaging and cult signaling. Similar to mobster covering their mouth and using code while talking outside card clubs. https://www.brandeis.edu/now/2021/january/trump-language-capitol-riot-mcintosh.html
It is important to understand silos. Outlets where social media and comms are targeted to a singular idea. Where people thing everyone strongly else agrees with them, even though they are a minority. https://www.nature.com/articles/d41586-021-00257-y
Silos are high energy: outrage, prediction and hot buttons hammering away on full send. Synchronized, targeted messaging that evolves around peer approval. Fear. Pedos. Secrets. Dissent is not allowed. Ambivalence attacked. https://www.aaldef.org/blog/emil-guillermo-trump-s-bawl-game-truth-silos-and-the-white-ethnic-press/
The normal approach to media would be that we are diverse consumers and always searching for "new". The reality is the opposite. Silos takes advantage of low cognition laziness. Marketers and social media invest billions into herding us into clusters. https://marketingland.com/consumer-content-breakdown-media-silos-converged-marketing-146601
2014:"the left and right ends of the spectrum...about 20% of the public overall, have a greater impact on the political process than do those with more mixed ideological views. Most likely to vote, donate to campaigns and participate directly in politics." https://www.journalism.org/2014/10/21/political-polarization-media-habits/
2020: "America’s relatively rigid, two-party electoral system stands apart by collapsing a wide range of legitimate social and political debates into a singular battle line that can make our differences appear even larger than they may actually be" https://www.pewresearch.org/fact-tank/2020/11/13/america-is-exceptional-in-the-nature-of-its-political-divide/
It is clear that the strategy of the last administration over the last five years has been to anger, divide and weaken America. His last act was to push the most radical supporters to violence to defeat the electoral vote. He will not be convicted but he will never be forgiven.
