I have my dream scenario in mind.
Fred Phelps and the WBC will picket the Islamic Center of America in Dearborn, MI, the largest mosque in North America, to remind the idolatrous, doomed Muslims that Mohammed was a pedophile and a false prophet. Like most other false religious systems of modern doomed america, Islam teaches rebellion against the Lord Jesus Christ. Muslims claim Christ was merely a prophet and that He did not die and live again. They claim His blood is not sufficient or even necessary for salvation. They shall learn the truth when Christ himself returns!
John 8:12 Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
John 8:24 I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am [he], ye shall die in your sins.
If you die in your sins, you go to Hell, for all eternity! There is no salvation or light in Islam or any other such false religion.
The best possible outcome?
Muslims from the mosque come out, swords drawn, and behead the Phelps Phamily Phreaks right there on the street as a warning to the rest of us infidels that they simply will not tolerate the exercise of freedom of speech that goes against the dictates of their faith.
Why is this the best outcome?
1) It gets rid of the noxious Westboro crew.
2) It makes it abundantly clear what is wrong with Islam.
