That said, I think there are already laws which will apply to islam. For example...
18 U.S. Code § 2385 - Advocating overthrow of GovernmentThis law alone would stop the practice of islam in a way that encourages the establishment of sharia law over existing law by jihad.
Whoever knowingly or willfully advocates, abets, advises, or teaches the duty, necessity, desirability, or propriety of overthrowing or destroying the government of the United States or the government of any State, Territory, District or Possession thereof, or the government of any political subdivision therein, by force or violence, or by the assassination of any officer of any such government; or
Whoever, with intent to cause the overthrow or destruction of any such government, prints, publishes, edits, issues, circulates, sells, distributes, or publicly displays any written or printed matter advocating, advising, or teaching the duty, necessity, desirability, or propriety of overthrowing or destroying any government in the United States by force or violence, or attempts to do so; or
Whoever organizes or helps or attempts to organize any society, group, or assembly of persons who teach, advocate, or encourage the overthrow or destruction of any such government by force or violence; or becomes or is a member of, or affiliates with, any such society, group, or assembly of persons, knowing the purposes thereof—
Shall be fined under this title or imprisoned not more than twenty years, or both, and shall be ineligible for employment by the United States or any department or agency thereof, for the five years next following his conviction.
If two or more persons conspire to commit any offense named in this section, each shall be fined under this title or imprisoned not more than twenty years, or both, and shall be ineligible for employment by the United States or any department or agency thereof, for the five years next following his conviction.
As used in this section, the terms “organizes” and “organize”, with respect to any society, group, or assembly of persons, include the recruiting of new members, the forming of new units, and the regrouping or expansion of existing clubs, classes, and other units of such society, group, or assembly of persons.
But wouldn’t the first amendment trump all those laws, since it is the Constitution - the law that trumps all other laws?
At best it would be a contradiction.
I firmly believe that that is our biggest problem with Islam.
We cannot fight it like we fought nazism or communism because as it is currently written our own constitution forbids us from fighting it.
For us it’s hard to come to grips with the realization that our most cherished and idealistic “right” as written is flawed, but if we don’t the Islamists will take over, or there will be a revolution.
