"I do not want my country run according to your religious beliefs."

Absolutely. In Germany, for example, Christian Democrats will tell me their party started -- historically through the Catholic Centre Party -- in reaction to the Kulturkampf or culture war initiated by Otto von Bismarck's penal laws. Later Bismarck withdrew the laws when Leo XIII persuaded some of the Catholic Centre Party to support Bismarck in the Reichstag. Today in Germany, there are other parties (besides the Christian Dem. Party) that endorse no religious values and are thriving among their own constituencies (remember, Germany is 35% non-affiliated; 5%, Muslim; 30% Catholic and 30% Lutheran.) What you need to do is convince American Non-affiliates (underrepresented in a very Christian Congress) to start their own political party -- and work toward removing the word "God" from documents, rituals, etc. Make your party's motto: "It [religious belief of any sort] has no business even being brought up." Go for it!
