Abso-fucking-lutely not. Fascists would NEVER be able to gain power in a truly democratic society. No ifs, ands or butts.
Fascists are funded into power (and into existence) by CAPITALISTS - adherents to an ideology that is violently incompatible with anything that can be called democratic with a straight face.
Brazil is not a democratic society. It is a (so-called) "liberal democracy" - something that can be more accurately described as 95% capitalism with some fake democracy substitute thrown in as a legitimising measure.
I'm afraid not. Liberalism is about as "authoritarian" as it gets - or do you classify the ongoing genocide the (so-called) "liberal democracies" are sponsoring in Palestine as (somehow) "non-authoritarian?"
Sadly, “liberal” partys nowadays are mostly economically liberal (i.e. freedom for corporations, deregulation etc.)
That is what they have ALWAYS been.
I’m not from the US
That doesn't matter. Liberalism is a right-wing ideology - even in Antarctica, on Mars, or on the other side of the galaxy.
There is no such thing as a "liberal" left. Liberalism is a right-wing ideology - that's why they are constantly "reaching across the aisle" to their fascist brethren.
(Apart from that I do agree with your point, though.)
Space lacks large groups of impoverished and repressed people whose labour you can exploit to make your mines profitable.
