Communism in Japan

Communism Is Alive and Well and Living in Japan/TIME
Hmmm, didn't people abroad know it? It is not just communist party but there are still many people in DPJ who used to be members of Socialist parties. Even I used to love Marxist thinkers. I still love some of them. But I dislikes their style of working out politics. They often go against realism and national interests. They want world revolution, they want to topple the regime at the risk of damaging Japan. They used to trust North Korea but didn't trust Japanese government. They tend to tilt toward China rather than the US.
I am not fan of LDP and we need a healthy opposing party. But I don't like idealists who has no sense of reality.
