Yes, because the subculture doesn't represent the majority. It's the opposite of "democratic"--it's a small group of people imposing their aesthetic on what you acknowledge is a "public form"--without the consent of the public. "Democracy" isn't about individuals or small groups making their voices heard. That might be a necessary factor, but it's not the purpose. Democracy is about the majority having the right to create the kind of society they want to live in. Maybe people in Sao Paulo like the graffiti (or maybe not, since the ban on other types of visual pollution seems popular). But it's the majority's decision to make.
