I have to disagree.
Let me see if I can explain: fight against CORRUPTION is like asking for a whore to be virgin.
Its the same as fight against VIOLENCE.
Do you think that the robbers will think: "Oh, I will not steal anymore because people are asking for less violence". Seriously?
Here is what I think: we need to be OBJECTIVE! Not fight against ourruption, but fight against CERTAIN PEOPLE (Sarney, Collor, Paloci and the whole gang).
Remember the "painted faces" while Collor was the president?
People were not fighting against corruption... its too 'vague', to 'general'.
They were figthing against a PERSON, a NAME.
I dont think Sarney will think "Oh, I will not take more money to me because people are using brooms..."
The message MUST be TO him, not to a 'general idea' because these basterds doesnt care!
BUT, if we scream "GET OUT SARNEY" instead of "get out corruption", it might work...
These are my thougts!
