Otaku: the most formal way of referring to 'you' in Japanese. Implying a technological barrier between people.

Another possible source of guidance for teenagers is television, but television's message has always been that the need for truth, wisdom and world peace pales by comparison with the need for a toothpaste that offers whiter teeth and fresher breath.
The Internet is a giant international network of intelligent, informed computer enthusiasts, by which I mean, "people without lives." We don't care. We have each other....

I agree that the fear of American cultural imperialism is shared by many people, and I agree with your point about the invasive nature of television culture. But I wouldn't draw the next inference: that this is negative and therefore it must be stopped. I feel that one should address this influence in a way that takes away the negative edge through a positive counter-response. This way, you reinforce and reaffirm your conviction in the inner values. You harness those beliefs and develop them with a greater degree of self-awareness. That's the kind of response people should have, instead of rejecting technology.
