Hold on, Bolsonaro is not a dictator. Federalism even recently screwed him over. He didn't act on COVID but individual states imposed their own measures and thankfully countered his opinion.
That's like saying Mussolini was not a dictator in 1922, because there were still so many factions competing against him in Italian politics. Possibly true, but it's also clear what direction he was heading. By 1925 he had largely consolidated his power.
Note: Trump's call for postponing the election is exactly the same thing. Evidence they have no interest in constitutional democracy and will, at the earliest possible moment, impose total control on the country.
