If the lunatic fringe of Muslim society is “only” 10% of all Muslims, that means there are over 100 million fanatical Muslims.
Since we have no way of knowing who is “moderate”, ie does not take the Koran seriously, and those who do take it seriously, we simply have to keep them out of our country.
Its pretty simple, its a matter of economics
Where Muslims live the good life (UAE, America as examples) you have very little, if any terror activity.
In particular America because we spend too much time worrying about paying our mortgages and making sure the ‘Rats don’t take all of our paychecks in taxes. Well at least this one tries to :)
The life is too good in this country to strap a bomb, or buy a rifle and start blowing people to smithereens.
If there really was an infitada in the United States, it would have begun and occurred long ago. There are quite a few vulnerable high profile targets and acquiring what is needed for a massive terror operation is not impossible
But again, American life is real good, even for the loons that live here (and there are plenty of loons in this country, but they are all pussies and like looking at internet porn)
