Propaganda is information, often inaccurate information, that a political organization publishes or broadcasts in order to influence people.

Point being, even if it's not necessarily all lies how do you know you're not being lied to or mislead when most propaganda are, by definition, lies and half-truths? I don't trust any sort of propaganda because chances are I'm being lied to.

People use words in different ways. You will find varying definitions of propaganda. Some people will call any information produced by a government propaganda. Some people will only call that information propaganda if it appears to have a notable bias. Some will only call the info propaganda if it contains outright lies.

You seem to want to define propaganda as any information produced by a government designed to pursuance people of something. Most people are not going to be against that kind of information (or at least not strongly against it). I’m pretty sure most people that say they are against propaganda view propaganda as information that is misleading or an outright lie.

The problem here seems to be that you have taken the stance that propaganda simply means “persuasion”.
