To get us started off I'll elaborate on my position a bit.
I am in favor of the impeachment of Dilma Rousseff, even though I'm sympathetic to the criticisms that she is the scapegoat of the economic decline in Brazil (that is largely a crash in the commodities market) and the incredible car wash scandal where over 5 billion was paid to corrupt politicians .
Many on the left accuse this of being a coup, and point out that many of the politicians voting for her impeachment are themselves under investigation for far greater wrongdoing than Dilma is being accused of. There are also legitimate accusations of misogyny against her and classism, as the workers party has never been accepted by the upper classes and extreme partisanship has always existed against them.
They may point out that the things Dilma is being accused of (irregular budgets where monies were borrowed from state banks to cover budget gaps in order to secure reelection) are things previous governments did with impunity and were not considered illegal.
Despite her crime being minor in comparison to the systemic corruption being unearthed across Brazilian politics I believe that her action was illegal (and that others doing it with impunity is not a legitimate precedent or excuse).
This has deeply divided me and many of my Brazilian friends so I hope we can discuss this agreeably even if we do not agree.
