The world is a web of information attempting to influence you one way or the other. Almost no information exists that is not tied explicitly to an agenda. Even information shared by benevelent creatures found to be beneficial for you specifically is tied to an agenda, that will likely profit from it. There is nothing wrong with that, there is nothing wrong with people pushing an agenda…we all are and we always will be. Good and evil do not exist, just control and freedom from control.
So what do we do? Avoid the information overload completely, live in a mountain cave meditating all day? Only if you want to. Otherwise it’s best, to simply accept that every piece of info is an attempt to sway you. That you must know yourself and seek the information that supports your values. Do not isolate yourself from the propaganda, interpret it and do the best you can with it.
