Isn’t propaganda just a form of persuasion? What about propaganda separates it from advertising or interpersonal communication?
Edit: Not all propaganda involves lying. For some reason, we seem to be more comfortable with a person lying to us than we are with viewing a propaganda poster that uses verifiable facts.
Edit 2: Another interesting note is that in some countries, propaganda is not viewed negatively like it is in English speaking countries.
That’s because the definition of discrimination you’re talking about is not the main definition of the word, and is not a good fit for the use you’re describing.
The word you’re looking for is differentiate.
intransitive verb To make a clear distinction; distinguish. “discriminate among the options available.”
To make distinctions on the basis of class or category without regard to individual merit, especially to show prejudice on the basis of ethnicity, gender, or a similar social factor. “was accused of discriminating against women; discriminated in favor of his cronies.”
To perceive or notice the distinguishing features of; recognize as distinct. “unable to discriminate colors.”
Seems like it’s primary use is to distinguish between things.
