If you're confused by the self-righteous of upper-middle class Brazilians about this, they had the same reaction to disappearances and torture during the dictatorship. You wouldn't dare take over a country without the support of the upper-middle class who will have to administer it. You can convince them of anything that doesn't affect their comfort at all. They supported Bolsonaro's coup, and now they'll support the destruction of freedom of speech in their country to keep Bolsonaro from speaking. They're actually beaming with pride about how they're not free to speak, similar to neocons in the US.
I thought Lula was mostly a good guy, but he seems more a passenger than a president at this point. The administration must be very confident of being able to prevent future elections, because they won my a tiny margin (just as Labour in the UK and the Democrats in the US), but they think they have the mandate to come down hard. Brasil nunca mais?
