Chaim,
American founders created a system that tried to take into account human frailties and make it work around dangers of both despotism and lawless anarchy. At previous times, democracy was not a discredited word: ancients tried it in Greece and Rome and it was eventually supplanted by “benevolent” Kings, who were expected to be responsible with the people that “belonged” to them, similar to how every balabos takes care of things inside his house for his own sake. Letting unruly masses to run the country was considered insane. Two attempts were made simultaneously: France and USA. French experiment ran indeed insane very quickly, leading to mass lawful and unlawful murder of lots of people, both from old regime and between revolutionaries themselves. It did work out in a long term. American experiment ran surprisingly better and USA has 250 years of elections, interrupted just once by a civil war period. Compare it with the history of European countries and all the wars and revolutions they generated.
So, there is clearly something done right in this country. Does it mean that courts and free speech rules are perfect? of course not. But it would make sense to learn first about how they developed in history. If you would like a kosher perspective on history. I would recommend Rabbi Berel Wein. I see that he has a book “The Golden Land: The Jewish Experience in the United States and Canada” also recordings on Torah downloads, etc.
