How do we feel about propaganda? And what would the definition be?

As far as I understand it, propaganda is simply a tool used to convey political messages accurately and concisely in hopes to get people over to whatever side it is coming from. Am I wrong in this?

Is there a “good” propaganda and “bad” propaganda?

EDIT: Rephrased some things

  • This might not be what you meant by “propaganda”, but when making assertions about historical events for some political purpose (e.g. to attempt to educate a liberal about imperialism), we have to actually show the basis for every claim and critically analyze all sources used (unlike bourgeois media, where they can say basically anything and/or use circular referencing). I think that should apply to media (news, etc.) post-revolution as well
