The Founders, who learned their history lessons from educated teachers, learned that the admixture of religion and politics doesn't really advance either one, and we wind up with the worst of both.The Founding Fathers 'admixed' religion and politics often. Look up the Virginia Statute on Sodomy and note Thomas Jefferson's hand in the creation of same. Maybe you were unaware that almost half of the original 13 States had mandantory taxes collected to support organized religion.
Every state that had an established church abolished it either before or within a year of ratification of the Constitution but one, Connecticut.

I suppose you'd support your personal denomination becoming the established church of the United States?
