I followed the link you posted, and with the exception of the banner to the other site about North Korea, and a goole page on "machine translations" everything links to some book selling site. The only thing that takes one to anything representing an opinion is the リンクポリシー (link policy). This page goes to a Japanese language page, which only then takes me to anything not trying to get me to amazon.com (if your visitors don't read Japanese, they will go to another site).
I admire your time you put into your site and I think you could add some interesting points to this forum, but if you want people to spend any time on your site learning, you need to make getting to your content easier. Why would anyone click on "link policy" unless they wanted to post a link? I had to systematically click on every link you had to find anything. Make navigation on your site easier and people will have a look.
I'll take some time and see what you have to say...
