Your use of the word propaganda in this context is itself progranda. You are using the negative connutations of that word to induce an emotional response to cause the reader to see your opinion, and your actions in support of your opinion as virtuous.
They may be, but it would be better to avoid using propaganda to counter what you see as propaganda, and stick to rational justifications.
