You claim that gun control does not work in Japan because the mayor of Nagasaki was killed by a thug. Japan has a crime rate drastically lower than the US, in every category. One incident does not prove or disprove a point.

It is true that culture plays more of a role in crime than gun availability. Countries such as Switzerland have high per capita rates of gun ownership and little crime. There are places with strict gun control that have lots of crime. However, gun control works in Japan. Whether that is due to culture or government policy, is beyond the scope of this comment.

You comments about eastern asia generally sound disdainful. I am a young white male who has a relative teaching english in Japan, as well as a few school friends of Korean origin. I do not know much about the darker-skinned peoples of east asian descent, but my conversations with my relative paint a very different picture of Japan than you do. You do not need to lock your doors in Japan. You can walk down almost anywhere in Tokyo without fear of mugging, rape, or assault.

Why is this? Because in Japan, people respect the law. My ethnic Korean friends had parents who stressed education, limited freedom, and consequently made good lives for themselves and their kids. You speak wistfully about asian immigrants "Being heirs to an authoritarian, prudish tradition and untrained in the privileges and responsibilities of liberty." That liberty, as you define it, being "oft-exercised libidos" and "thongs and glocks."

I think Americans can learn a lot by studying the behavior of their east asian counterparts, not the other way around. I would gladly do away with thongs and glocks if it meant less crime, better school performance, and fewer teenage pregnancies.

I realize this is a long post and a reply to a dated essay. I hope you find this and decide to reply, because I am eager to hear your rebuttal.
