Are you sure poignant is the word you mean? "evoking a keen sense of sadness or regret." The US Declaration of Independence is a denunciation of tyranny and a justification for rebellion. I don't see much poignant about it.

You're right; I changed it to a different word. Thanks. [Also wow... it seems this is the only negative-score question on the site. That's an achievement right there.]

Do you already have formulated the "ideal" you mention and what specific group you are targeting? You are basically looking for standard rhetorical devices, though with a focus on stuff that has been used in previous decades and centuries as propaganda - or just plain advertisement these days.

The question to ask yourself is: "Why should this thing be important to my target audience and what makes my side better at that thing than the other side?" If you are bent on rebellion you could change that a bit to "and why is the other side so bad at it that we need to do something ourselves?" Everything is moving to people if it feels like someone has figured out what you want even though you didn't even know yourself that you wanted that thing.
