“IF YOUR GOAL was the eventual overthrow of the government and establishing Shari’a Law as the law of the land, but you didn’t have a large enough majority to do it by voting or by force, how could you do it? One good way would be to keep pressing for small, incremental concessions. And when you gain one, to hold it, and try to gain another.
And if you were using this strategy, what is the first concession you’d try to gain? I think it would be to establish laws and cultural norms that prohibit criticism of your group or its goals in speech or writing. This could effectively prevent an organized effort to block the next concessions you try to gain.”

Pay very careful attention to this: when you let our leaders make concessions to Islam, and do not object strongly, you are letting them allow Sharia Law on American soil.
