What makes graffiti a powerful tool for dissent?

Graffiti is called a subversive art form because it challenges power and authority by spreading messages that are often censored or suppressed. It is actually done secretly without permission.

Speed is important in graffiti creation because artists work quickly to avoid being caught or punished by authorities since graffiti is usually done secretly.

Graffiti is important for the marginalized community because it gives them a voice to express their struggles, demand justice, and show unity with other oppressed groups.

In graffiti, "immediacy" means doing the artwork quickly and with urgency, without delay, to express emotions or messages on the spot.
