I do study history, I just don't see the cyclicality of it. I think it's an illusion that people want to see. The late 19th century was a period of extreme nationalism. There wasn't a similar period 100 years before, and there isn't one 100 years later. I think it's very dismissive of the progress we've made intellectually over the past century to think fascism/communism/tyranny is going to come back. I think it's completely unsustainable in our current (and future) society so there is no fundamental reason to militantly guard privacy against some illusory future evil that won't come about.
