Answer:
The rumble is important because it shows that they still exist, in a way?
Step-by-step explanation:
The Greasers goal isn't really to make everyone equal, though they wish they could. They just want Socs to be aware that they are people with feelings too. Though they don't have all of the 'perks' of Socs, they really just want to be recognized. By showing their dominance in fighting, they show what their known for. Hope this helps+makes sense!
