I think there have been societies with genuine protections for free speech, and even in the USA there have been better times and worse. So I wouldn’t say that shutting down free speech is “what we are as a species.” As a species we have many impulses to be hostile to those we disagree with, but we also have the ability to see past these and to build societal systems that protect people’s right to speak freely. It’s up to us whether we pursue the latter or give up.
