Society is in a total war over facts and spin. Virtually every aspect of society that has any influence is infected by it. Many (not all) want to push their own agenda, to control the narrative. We are bombarded by propoganda throughout much of our day. This has been the case for a long, long time, but it seems to keep intensifying. We live in an age where science has even become politicized over ie: climate change.
None of us have been immune to it. Film, TV, news, message boards, twitter, academics, elementary/high school, religion, parental upbringing. You are brainwashed. We now get to choose more of the brainwashing we consume based on whatever confirms our biases. Do not tell me all the facts, just tell me what I want to hear.
Most people are such selfish delusional a-holes that they will argue against the BS spewed by the side they dislike while drinking up and defending the BS of the side they prefer. You are a soldier in this war, whether you know it or not.
