The last time I was in Sacramento, California, I noticed billboards with the message "Get To Know Islam" nearly everywhere I went. I do not want to "Get To Know Islam" any more than I already do. I know enough. I know that Islam is a legal system that has not changed since it was conceived of in the 7th century, and that there is not one single Muslim country in the world where any sort of modernized, civilized interpretation is practiced.
Even in Turkey, which has a secular government, things like honor killings are common place, and are part and parcel with Turks who emigrate, for example, to Germany. I know this because I used to read about these honor killings in my morning newspaper. Girls stabbed or shot, usually because they were caught dating a non-Muslim.
What you see in the picture above is a set of laws. They are being plastered all over in London and other cities by "radical" Muslims. In reality, it is the first attempt to carve out areas of Britain and impose Sharia. These areas, once established, will grow in size and influence until the UK has been defeated.
Just because you think it'll never happen here, does not mean that it won't. If you had told me in 2001 that they would be building a giant Mosque on the ashes of the world trade center, I would have thought you were nuts, too.
