I've been in China and Hong Kong and Taiwan, I've been in Argentina when people who were leftists were disappearing, I've been in South Africa during Apartheid where blacks had limited or no rights, and in Rhodesia where the whites were buying weapons to defend themselves from the armed guerillas from Mozambique, and I've been interrogated by the military in Brazil* and in Turkey. And I'm banned from traveling in that bastion of hypocrisy, Canada, where the customs agents work tirelessly keep out the Pakis but welcome the Chinese if they bring enough money. And yes, the basic divide between people is not just blue vs red.
When I first started visiting other countries (for business), I was amazingly naive. I thought the divide was between Capitalist Democracies and Ant-like Communisms. My first exposure to other countries caused me to think that the divide is rather between places where men are above the law, and places where the law is above men. Argentina is a mafia, and Turkey is not far behind. If you have money or connections, you can kill people. South Africa, in contrast, actually has rule of law.
I've since broadened my definition of the divide to be between Authoritarians who can never live comfortably in a liberal democracy, and those who are more open minded. I think this is the basic divide, and all others are built on it.
I'm a really smart guy. I've been all over the world (the list of countries above is less than half of those I've seen) and I've been doing this for more years than you've been alive, and this is what I've come to believe.
Your mileage may vary.
