Abstract
This paper is a critical and comparative legal historical study, which offers a global vision of the U.S. Legal System, according to the religious factor impact and its complex dimensions (e.g. religious liberty, Church-State relations, welfare state & solidarity). The principal goal is the deconstruction of the fake official History, elaborated after the Second World War (e.g. inferences, impostures, fallacies). At the same time, it shows the social development (and the kind of commitment in each period), and how it happens the consolidation of the system thanks to the regulation. In this way, it is possible to pay attention to the American experimental evolution (not lineal or exceptional –as many U.S.hand-books pretend): from colonial Blue Laws (or Sunday regulation), up to the current regulation on freedom of religion and non-discrimination. Also, this paper offers a systematic set of diverse legal sources (e.g. Executive orders & rules, Legislative statutes, Judicial cases & resolutions). Another goal of this paper is the evaluation of the allegedly paradoxical policies and regulations in this field, during the last two Administrations (Clinton and W. Bush); both of them, from extreme views (linked at the end), they used incorrectly the religious factor, and they confused the institutions. The result seems to be a landed in the Postmodernity (less realistic and more speech based)
