The Liquid Laser has his facts straight!
Seperation of Church and State was origionally advocated by the religious because many of them had faced persecution in Europe and had SEEN what happens if church and state are too close to one another. You get this point a lot when you read Madison's notes on the writing of the Constitution (highly boring, but it adds an entirely new context to the constitution... not to mention it amuses me when the SC judges claim to KNOW what the founders wanted without reading anything other than the constutition that they wrote apparently.....).
On another note- not even Machiavelli thought that combining religion and state was a particularly good idea- noting that they corrupt and weaken one another.
And I have no idea why IlyaK decided to "bestow upon us" his 10 year plan for the country....
