Not only are neo-Nazis in Brazil numerous, but they receive open public support from the Brazilian government for their nefarious activities. Indisputable evidence of this trend can be seen in the photo below, which shows neo-fascist army recruits sieg-heiling the Brazilian flag:

Rocha includes the context for this disturbing image:
When you turn eighteen in Brazil you need to register for the armed forces. Whether they draft you or not is up to them
You can say you are a homosexual (and get a red stamp on your army papers saying so) or that you are a pacifist (ten years without civil benefits) to avoid it.
If you do not use these arguments, you register with the armed forces and then take the oath to the flag before being liberated (or not).
Yes, this is satire. See this comment for a helpful explanation.
