Calling Dilma Rousseff's impeachment a coup is more than enough to acknowledge that the analysis lacks any semblance accuracy and boils down to partisan rhetoric.

If both houses of the national congress of Brazil, whose members were democratically elected and represent the people of that nation, support and greenlight the impeachment process based on widely known corruption charges, and if Dilma Rousseff's government fails to secure minimal backing among all elected representatives to cancel the impeachment process (she only needed 1/3 of the votes), it is patently obvious that this is the democratic process working as expected, and as specified in Brazil's constitution.
