I see what you mean but I disagree. I am a proud Ideologue.
Every person should have his very own ideology in my opinion and it is ok to promote it. If you start manipulating information with 'evil intention' it becomes Fake News
If I take your definition of Propaganda and add my Fake News one, I would argue.
Propaganda = OK
Fake News = bad
morally
It seems like you're thinking of the word "system" in more individual terms than what I meant. I was thinking of large-scale systems that people subscribe to, buying into a bundle of ideas they haven't bothered to unpack and understand, then ending up under someone's control. If we're talking about systems we create for ourselves, I would agree with you. It's when we push our systems on others that our actions appear as an attack on one's free will.
Yes, we can try to help people by sharing what we've learned, but if they're not asking for help, you can expect resistance or even flat out denial. It is far more effective to respond to requests than to offer answers to people who have not yet discovered the questions. This also reduces the risk of making unintentional assumptions about the person you're trying to help.
signing your believes off to a certain group or massivly shared idea without questioning it makes a person literally retarded. (they effectivly lack part of their brain capacity)
But then I would only answer to posts and never make one :D
Making a post is not pushing people to conform to your system. It's simply sharing your perspective with anyone who chooses to read. Anyone who wants to can benefit from your perspective. Anyone who is not interested is free not to read it.
Forceful or extensive pushing of your own agenda is a very bad habbit, I agree. You should always be open minded to change your beliefs.
