The Dark Side of Democracy
This was shown most clearly in the French Revolution. And this almost transferred to the new United States in the 1790s, as Washington: A Life relates.
Thomas Jefferson was a radical republican, and was strongly in favor of the French Revolution, excesses and all. Many Americans agreed with him and organized Democratic Republican organizations almost everywhere in the North. These quickly turn into mobs in the streets that were determined to take over the government violently.
The government in Philadelphia was only saved by a severe outbreak of Yellow Fever – that brought the people back to their senses.
We have progressed since then. The people are just as foolish – but they are easily controlled by the Media.
