I think one of the initial cracks for me was The Corporation documentary. It mentions "Confessions of an Economic Hit Man" while talking about privatizing water rights (including rain water collections) in Bolivia. This directly connected the internationalism (learning about things) to the anti-capitalism that was starting to form in my mind. Once you start to realize the myths at the core of domestic propaganda, suddenly you start questioning a lot of things. The later part of this learning phase was understanding media literacy and cultural hegemony. Ways of Seeing was super useful at this point.
