When I was still a girl, I used to hate the US with a passion. I too hated Americanization. I too disliked their ways and impositions on us, to the point that I could not bother to learn English, not even to attain good grades at school. English was my worst grade back then.
Then it dawned on me... It was kind of hypocritical (and rather ignorant) of me. So I learned to embrace the good and the bad, be thankful, and while I still wish we would be a proud and independent nation, and disapprove of many things, I have learned to live with them, until an opportunity for change arises.
But, back to Miyazaki: I kind of like that he rants about these things, and that he is honest about his opinions. From one opinionated person to another, I say, "Keep them going, bro!"
