Our society is not without faults. Our domestic and foreign policies are also often flawed. To correct failings, we need people who point them out, however unpopular that may be. We should be enabling a wide framework of public discourse, not seeking to silence people. To date, we haven’t quite reached the level of hysteria of 1950s McCarthyism, but we are perhaps coming close.
Liberty and longevity are not directly related. History has in fact shown the opposite. Like… capitalism is only a few hundred years old at most, and has only existed in its current form since the 18th century. Compare that to systems of fuedalism, monarchism, places that have had oppressive regimes since conception like Saudi Arabia. Also look at how our current form of capitalism has subsisted largely on the backs of usee countries being bled and made to kneel by usar countries, which is arguably the largest contributor to its perceived longevity.
Sorry, by “persisted” I didn’t mean to imply that it’s the oldest. More that it is surviving where other systems have failed.
