healthmyths does not understand the Constitution.
We can block anyone because they may be a threat.
We cannot block religionist per se.,
Why not?
From the Constitution:
"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof" his or her choosing.
It ensures the autonomy houses of worship and other religious institutions from government in matters of internal governance and religious law.
It prohibits government from enacting laws that specifically target religion. Importantly, it empowers the government to provide houses of worship with special
accommodations and exemptions from civil law that might otherwise interfere with religious worship or practice.
The Establishment, Free Exercise and Religious Test Clauses all complement one other to guard against "[a] union of government and religion," which in the words of distinguished U.S. Supreme Court Justice Hugo Black, "tends to destroy government and to degrade religion." Engel v. Vitale, 370 U. S. 421, 431 (1962).
The United States Constitution also contains a provision called the "Religious Test Clause."
It prohibits any kind of religious test for citizens to hold elected public office, or to be a public official or employee.
Found in Article VI of the Constitution, the Clause states: "[N]o religious Test shall ever be required as a Qualification to any Office or public Trust under the United States." So for example, the government cannot require a citizen to be Christian, Muslim or Jewish, or subscribe to particular religious beliefs in order to hold public office.
It also cannot disqualify a citizen from holding public office because he or she is an adherent to a specific faith (e.g. Christian,Jewish, or Muslim) or holds particular religious beliefs.

Where does the above Constitutional amendments STATE anything about keeping religious people out?
As Andy McCarthy points out, the U.S. already asks asylum applicants about their religion. They do this to determine whether the applicant is being persecuted for their religious beliefs. The reason they ask is that we, as Americans, find oppression of people on the basis of religious faith morally wrong and unacceptable, and we want to protect people who are threatened because of their beliefs. The inquiry is to determine whether they are being victimized for their religion, NOT to determine whether their religion is acceptable to American authorities or compatible with American life. Ultimately, a significant number of Americans currently think that the Muslim faith is incompatible with American life and values, and even that Muslims are inherently enemies of the United States. (If you really believe that, why would internment camps be ruled out of the question?)
