The colonies were to a large extent, settled for reasons of religious freedom. Various protestant sects fled the persecution they received in England (COE) and a few other European (Catholic or Lutheran dominated) countries. Even Catholics fled from England (Mary's Land, anyone?).
From that perspective, it is a lesson for all of us how the LDS were treated by the then, mainstream religions.
It is also a lesson on how government, entwined with religion (Separation Clause, anyone?), becomes the same persecutor that many fled from, a mere two hundred years previously.
One does not need to defend the LDS or even agree with their precepts. One only needs to recognize the absolute violation of our Constitution and our espoused Freedoms and Liberties.
One other item should be recognized. Much is said against the practice of polygamy. Rightly or wrongly, it is the way western culture has come to accept. But it is not the only way that exists. Nor is it even, in view of the entire world's cultures, past and present, a majority practice.
This religious practice was before the Supreme Court in
REYNOLDS v. U.S., 98 U.S. 145 (1878). Here the Court argued that because plural marriages were condemned in English Common Law, more specifically, English Religious Canons, the practice would be forbidden under US Law. The Court decided that the Government could reach not into opinions, doctrine or theology, but into actual practices:
"Coming as this does from an acknowledged leader of the advocates of the measure, it may be accepted almost as an authoritative declaration of the scope and effect of the amendment thus secured. Congress was deprived of all legislative power over mere opinion, but was left free to reach actions which were in violation of social duties or subversive of good order."
N.B.: The "acknowledged leader" was Jefferson. This was the first time the Court had used Jefferson's letter to the Danbury Baptists... That "Wall of Separation" clause stems from this case and not from Everson v Board of Education; 330 U.S. 1, 18 [1947]), as many think.
The history of this period is fascinating. For instance, compare the above ruling to current rulings on the gay marriage issues. It is obvious to me, that Reynolds must be revisited. What the result will be, is likely to turn this nation on its head. So I agree that this thread is extremely relevant, and even timely, to issues that confront us today.
Keeping always in mind: Those that do not remember history are doomed to repeat it.
