Ask yourself what happened to the "Church of England" after the American Revolution?
Since the founding father's did not intend the Constitution to be a suicide pact, it was "shut down."
The justification: The Church of England was not just a religion, it was a political religion requiring complete allegiance to the King of England. The King's followers were pledged to aid him in destroying that Constitution and the American Republic and thereby forfeited religious protection under the Constitution.
Church of England congregations were compelled to abandon all their political pro-King doctrines (thereby becoming the Episcopal Church) or leave the country.
Why should the situation with Islam in the US be regarded as different? Why should we now allow the Constitution to become a suicide pact?
This is starting to feel like we are in Jonestown, Guyana.
The problem with that being that it was not shut down, and American Episcopalians had begun separating themselves from the Church of England before the Constitution was ratified. So as a precedent for how to deal with Islam it falls far short.
