"#passelivre You cannot oppress the people for a long time without expecting them to answer that oppression one day," Acton Lobo tweeted on Friday.
Not everyone is psyched about the protests, though. The government, for one, has adamantly criticized the methods used by demonstrators, citing violence and destruction of public property as undemocratic behaviors.
"We are always open to dialogue, but [we] will never tolerate vandalism," Sao Paulo Governor Geraldo Alckmin told Brazilian newspaper Globo.
Many civilians also oppose the Free Pass Movement. For some of them, the clashes against police and the overall enthusiasm show nothing more than a juvenile immaturity that is associated with leftist idealism in many South American countries.
"Anyone who is older than 20 years and is defending things like "free pass" simply does not understand how the world works," @razev tweeted.
Negotiations are currently stalled, since, according to the government, leaders of the Free Pass Movement have refused to negotiate.
The group has already called for a new demonstration in Sao Paulo on Monday at 5 p.m.
