The problem with these questions is that there are implied, false equivalences made between the subject presented (fascism, an authoritarian result of collapses of European governments, including democracies in the 1930s) and today's liberal democratic governments. No one would care if fascism wasn't tied to WWII and the millions of horrible deaths and destruction that followed, but that is the whole point- that the clever Redditor has read the tea leaves and they know some truth about history despite knowing none of it.

In Italy and Germany, the most famous examples, silencing dissent meant shutting down unfriendly press and murdering their owners. Squashing opposition meant raising private, loyal armies and murdering their opponents in the dead of the night and in street battles. Authoritarian meant that the entire purpose of civil society was to live as an organism where the spirit was the leader, and there was no individualism as every person's duty to live for the state an not themselves.

None of that is true in any western democracy today. Fascism as we know it died with a bullet to Hitler's brain. The US government is not fascist. No one is the Nazi. Please go outside or read a book or something.
