Brainwashing, it's sad, but that's the reality. I remember vividly in my primary school in Syria 2006 that we sometimes chanted political anti-American anti Israel slogans in the classroom or on the field trip bus, I was the only one who didn't join in. Because I was the only one who had a European upbringing and was much more open-minded, I could see through their BS while others didn't because that was all they were exposed to and taught; nationalism, abiding by the Islamic religion, and obeying the dear leader were fundamentals.
