Again, DL, read if you can the history cited in the Everson opinion. The whole point of the Establishment Clause was to avoid the Christian bias inherent in those state constitutions.
So you are telling me that States which had just placed explicitly Christian requirements into their own state constitutions, decided to ratify a Constitution that would remove those requirements?
That does not seem reasonable.
Again, what boggles me is why this isn't universally hailed as a good thing. Why the hell do conservatives want the state entangled with religion? And, just as crucial, why the hell do religious conservatives want religion entangled with the state?
You are oversimplifying the motivation of others. It is more complex than you make it out to be. I'll take but one example for the time being.
I am against slavery. I consider it wrong, and we should not tolerate it. This does not mean that I agree with the manner in which this goal was achieved. In fact I consider the manner in which it was achieved to be a complete bastardization of the legitimate process.
So too do I view this religious argument. Judges of the Federal government lied about the original intent of the first amendment, and used the power at their command to force it on the populace.
Now perhaps having religion separated from Government is a good thing, as you claim, but overturning the will of the people for their own good, and through an illegitimate process, is most definitely not a good thing.
If the result was not accomplished through the correct process, it is illegitimate. Whether it's goal was worthy or not is immaterial to the fact that they did not gain the consent of the people to establish this new condition, they imposed it on us without our consent.
