use details from the text to derscribes why ponyboy insists that being a greaser has nothing to do with "playing hero "

I think your question might primarily refer to chapter 7. Pony is awestruck about the article in the paper proclaiming Johnny, Pony, and Dally heroes. The subtext of the article was the irony that Greasers could be heroic. By now Pony has had enough of labels. Pony thinks that anybody can be a "hero" if they have the attitude and personality to be one.
