USA Today has a great article talking about the most recent ruling concerning gay sex laws in the US. The problem that is pointed out is not the fact that gay sexy laws were stuck down (a positive development in my opinion) but that the Supreme Court decided to reference foreign law as a justification for the decision.
This is a problem that strikes at the very heart of the seventy of the US. I am personally very concerned about the continuing trend of global rule that seems to be becoming more prevalent in the world scene. History has taught us that diversity creates strength by limiting the amount of influence bad decisions (and for that matter good decisions) have on a society.
It is therefor important to the US to continue to make decisions that are in the best interest of the United States (and for France, Germany, China to make the decisions in the best interest of France, Germany, and China) because it will ensure a certain amount of diversity among the countries of the world.
