This comment reminds me of Carl Schmitt's observation that nothing in a Liberal Democracy prevents it from becoming totalitarian (or otherwise.)
His books are more relevant today, as the state is re-establishing its authority to define "friend" and "enemy". "Good" and "evil".
Tolerating the "other" side's views is no longer acceptable.
The state is re-establishing its authority (and monopoly?) to determine public "friend" and "enemy".
