after watched the film, i intended to boycott coca-cola on my own, which is a symbol of american life-style and amerticanization. it is easy to refuse or contempt a single product, however, it is not so easy to resist the whole real world and your desire inside. finally, one will become a slave of freedom and demoncracy in american propaganda, even worse, lose his passion and idealism. it's not a good practice.
Science and Demoncracy, neither of them can be taught by other people. one is objectively difficult, the other is subject to their preferences.
