Unfortunately, that text would be in conflict with the existing First Amendment. In my view, it is necessary to exclude Islam from membership in the set of recognized religions. An institution which is not a religion is not protected by the First Amendment's free exercise clause and may be proscribed by law.
Closing Mosques, Islamic Centers & Madrassas is not sufficient action to solve the problem. So long as individual Muslims are present among us, free to indoctrinate their children and proselytize, the threat will not be reduced, it will increase. Resident Muslims constitute a fifth column, each one a sleeper cell of one, capable of activation at any time, unpredictably. We remain at risk until they die, emigrate or sincerely & finally abjure the doctrines of Islam.
Islam is what Moe preached and emulated, enshrined in the Koran & hadith; codified in Shari'ah. Until you will read a sufficient sample of Islam's canon of scripture, tradition & jurisprudence, your knowledge of Islam is speculative and probably false. Islam is not moderate, it is aggressive, intolerant and violent by design.
Shari'ah requires Muslims to participate in annual attacks against disbelievers; neglecting to do so when it is possible is sin. I refer doubters & dissenters to Reliance of the Traveller, O9.1 It is the duty of the caliph to make war upon Jews, Christians & Zoroastrians until they become Muslim or pay the jizya as prescribed in 9:29. Let doubters & dissenters read O9.8. It is the duty of the caliph to fight all other people until they become Muslim as prescribed in 8:39. Let doubters & dissenters read O9.9. Once you have opened and loaded the file, you can use the Windows search function to find the reference letter & numbers using the Ctrl f key combination.
Islam is supremely intolerant. 3:85. And whoever seeks a religion other than Islâm, it will never be accepted of him, and in the Hereafter he will be one of the losers. Islam denies your right to live and own property. Let doubters & dissenters read Sahih Bukhari 1.8.387. "I have been ordered to fight the people till they say: 'None has the right to be worshipped but Allah.' And if they say so, pray like our prayers, face our Qibla and slaughter as we slaughter, then their blood and property will be sacred to us and we will not interfere with them except legally and their reckoning will be with Allah."
Given the fact that Islam is intolerant & violent, dedicated to the destruction of our system of government & economy and Hellbent on enslaving us, tolerating Islam is suicidal idiocy.
The first corrective measure known to me was proposed by Pedestrian Infidel in the spring of '07: A Proposed Constitutional Amendment. Although I disagree with the fourth article of that proposal, I have endorsed it, because it was the first and remains the best option.
