I think I was quite clear in my conditions for what is propaganda, that being media produced and funded by big business. Nowhere did I say “everything” was propaganda, as you deceptively claim.
Arriving at truth is not such a simple thing as picking some narrative to believe and clinging to it uncritically, even though many, including apparently yourself, approach it that way. Rather, to arrive at truth, one must critically evaluate what one is told and the evidence one is provided. In this regard, the scientific method is an excellent tool for iteratively approaching truth.
Hopefully you can see that it is possible to develop a world view that approaches the truth without uncritically swallowing what someone is paid to tell you is the truth. Sadly, I rather doubt that you can see that, though.
