I have issues with numbers five and six:
5. Science, as defined by the American public school system, excludes supernatural explanations.
6. Science depends upon the “Scientific Method” for determining truth.
In the first place, the American public school system has no authority to originate a definition of science. Further, science by any definition does not exclude supernatural explanations a priori. It accepts any explanation for which there is evidence. Finally, the scientific method is not used to determine "truth" in an absolute sense but to discover the most likely explanation for natural phenomenon.
These two theses smell rather like the creationist whine, "They're teaching my kiddies that evolution is absolute truth and that there is no God." In other words, political propaganda.
