I would add to this list visiting the Casa de Leon Trotsky in Mexico City and seeing the book cases filled with books and journals, a Spartan bed, a work desk, Earl Grey tea on a table. Or a dust-covered statue of Lenin inside the dilapidated Vitebsky Vokzal train station in Leningrad (now Sankt Petersburg) - one of the last remaining ones - and someone placing a bouquet of red carnations under it.
We may disagree with their politics, or point out their errors, but at least they pursued a heroic vision of a just society - regardless of where that society may be geographically located. That is what makes me "choke up" - especially in the era whose heros are sycophantic corporate nullities concerned only about lining their own pockets. As Nietzsche said "The errors of great men are more venerable because they are more fruitful than the truths of little men."
