Earlier quoted context omitted.
Great points. There are plenty of areas to discuss politics, and at work doesn't have to be one of them. I've studiously avoided talking to anybody at work about politics, as it usually only serves to anger people if you don't agree. I've had a successful career of doing that.
That sounds like a fine approach, but unfortunately politics creeps into more and more aspects of life, hardly any topic remains apolitical. Like that quote "you may not be interested in war, but ..."
Do a historical survey of people who tried to suffuse politics completely through the lives of their followers. For completeness, look also at the actions of religions in the same way.
Power corrupts. Absolute power corrupts absolutely. Politics, movements of any kind which demand the entirety of the lives of their followers are often perpetrators of the worst things.
As a counterpoint, look to times and places where people are free to be open, to be themselves, and to choose how they live. There is also a power in the dispersal of power. Many call this freedom.
Like that quote "you may not be interested in war, but ..."
The way Robert Heinlein put it was something like this: "The end product of politics is like the result of peristalsis. It's not very pleasant, but it's no less vital to your health and well being." I think this is a good analogy. Imagine having a cocktail party conversation with someone singularly obsessed with their digestive tract.
