What was the Brazilian government's reaction to the debut of the blocos afros in 1975? They denied the existence of racism in Brazil and suggested that Ilê Aiyê would experience difficulties if they continued to operate as they did. They celebrated Ilê Aiyê as an example of Brazil's rich Afro-Brazilian cultural heritage. They did not comment on their political statements but suggested it would be best if they brought back traditional Carnival instrumentation. They acknowledged the existence of racism in Brazil but offered only indirect words of support for concrete programs to end it. None of the above.
