First consider these representative passages from the Koran.
Q.8:12 “I will instill terror into the hearts of the unbelievers: smite ye above their necks and smite all their finger-tips off.”
(Notice the word "terror" is actually part of Islamic theology! Thus calling a Muslim a "terrorist" is sort of like calling a Christian a "baptized believer"; see Mk 16:16.)
Q.5:33 “The punishment of those who wage war against Allah and His Messenger, and strive with might and main for mischief through the land is: execution (by beheading), or crucifixion, or the cutting off of hands and feet from opposite sides, or exile from the land: that is their disgrace in this world, and a heavy punishment is theirs in the Hereafter;”
Q.9:123 “Oh ye who believe! Murder those of the disbelievers and let them find harshness in you.”
Q.2:191 “Kill them wherever you find them, and drive them out from wherever they drove you out.”
Obviously Islam is more than just a religion, but a political ideology that contains its own crimes and punishments, and therefore subverts the US Constitution. Obviously that's the FBI's job to rout out those engaged in subversion, but also obviously they are not doing that. It's going to be up to our nation's leaders to get serious about this threat to our country, which means their constituents will have to put pressure on them to do just that, which at this time they are not. I think it's going to take a local homegrown Muslim killing millions with some WMD to get Americans to see through the taqiya and take action.
As a minimum, you would hope the mainstream media would simply quote from the Koran so that people would know what it says, but they rather focus on fake news than the real thing. Also, as they are mostly anti-Christian, in truth they support Islam because "the enemy of my enemy is my friend".
America should be a sanctuary country for those wanting to escape the evil religion, without having to worry about being murdered for apostasy. Muslims in this country should be parachuted into Saudi Arabia if they won't self deport.
Another option might be to create a modified Koran (call it the "American Koran") that removes all the calls for violence in the book, and create a new religion (call it "American Islam") for those wishing to continue in that faith, but with only the peaceful elements of the religion. Any mosque caught preaching from the old Koran would be immediately shutdown and the members deported.
Do we really want to wait until millions are killed by Muslims (or maybe just one Muslim) until we take action?
