Rebel without a Cause

Right now I am watching the live-debating TV program "the Future of Japan." Today's theme is the Japanese youth. To tell the truth, I dislike a few of the young participants who disagree with and reject opinions expressed by older participants without ever explaining coherently their disagreement/rejection. Indeed, they sound like merely complaining. (Of course, I don't expect them to suggest alternative ways of reorganizing Japanese society... which is extremely difficult.) Again, I see a failure of Japanese schooling to produce people who can engage in discussion.
