We think "Brass Knuckles" is a good text about what it means be brave, although its characters are teenagers and context situation recreates a teenager world, is possible to extrapolate its moral to our adult lives our situations and problems.
There are different ways to address our dificulties especially those who assault our freedom and dignity and always it can respond violence with violence if we make a literal reading of the text, but following the moral that the author says at the end "there is always a jujitsu for all Red" we are invited to be creative and find how to keep our beliefs whit us a do what we must do to maintain our dignity and self esteem.
