There is one thing that stands against your proposal:
The First Amendment.
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; ...
It leaves no apparent way to discriminate against Muslims. But, somehow, we're going to have to figure out a way around it. Or, put another way, figure out a way to discriminate against Islamic terrorists...
We have to amend the 1st to exclude islam.
“The First Amendment...leaves no apparent way to discriminate against Muslims. But, somehow, we’re going to have to figure out a way around it.”
There are well established exceptions to unlimited free speech (slander, incitement, fighting words, yelling fire in a crowded theater).
We just have to recognize when something claiming to be a religion has gone beyond what is reasonably within the bounds of religion to be protected.
Islam incites to violence, infringes on individual and human rights, and is subversive to the State. If legal determinations were made that elements of the Koran constitute hate speech, incitement or treason; then promoting it (or those particular elements) could be outlawed and legally sanctioned). Indeed, on the basis of any individual incident this could be determined in court, but being reversed could set legal precedent in the other direction.
Bottom Line: The truth about Islam needs to be admitted for the law to work against it.
It is a totalitarian political movement that has co-opted religion into its movement, and adopted criminal practices. Those political and criminal elements must not receive the protections of religion. Religion is protected to protect the individual’s freedom of conscience, not to shield criminal behavior from enforcement.
Mohammed = Charles Manson
Islam = 1.2 million strong Manson Family
