A Wikipedia webpage listing terror groups throughout the world counts no less than 112 Islamic terror groups.
Islam was started by Muhammed, a tribal warrior seeking revenge and treasure from fellow tribes, and within a very short time, its vanquishing hordes washed through Europe, imposing their own form of religious law and subjecting those conquered to a choice of conversion or servitude. It is laughable that Muslims now blame the Crusades for their bloodthirsty ways today.
The Crusades were simply a retaking of formerly held lands from the Muslim marauders, but for some reason much of the Western world accepts the claim that the Crusades were the height of evil and vicious treatment of a peaceful, religious people who only wanted to share their beliefs with the infidels of the West. Islam has only been peaceful when it has been subdued by conquering military might, and that is what will be required to quell the current insurgency we see today.
One of the biggest farces now confronting civilization is the demand by Muslim groups that Western countries hosting sizable Islamic populations allow them to self-rule and establish Sharia law for Muslim members of the society in total disregard of local and national laws.
This, too is a form of invasion, and it is entirely preposterous! While subscribing to their cultural and religious norms may be reasonable if they do not conflict with local law, the idea that a people or culture can decide what laws they will and won’t follow is beyond belief, and yet, there are Western nations and people willing to pander to this type of nonsense and to accommodate the farce.
Sharia law in Germany, page 2:

F**k these imbeciles! Sharia police?! Islam must become extinct! Those that practice Islam must be rehabilitated and those that commit crime in the name of Islam must be executed!
Time for another Krystalnacht this time against muzzies who deserve it!
Dont you think Hillary Clinton will do the same thing to America. What does the Muslims have over the world to make us there slaves? Do they have atomic bombs placed strategically around the world?
Lol wha t a joke. Think Putin would put up with that s**t
Europe would be speaking German today if they would have left the Russians alone. Russia was$#%&!@*s Waterloo. Ordinary Germans, British etc are beginning to stand up to the increased crime and the changes in their way of life. Europe is no melting pot that America is. Their pot is beginning to boil over.
goodness, you mean in Germany they use English,,,,now this could not be photoshopped could it.
They would be good target practice in the U.S.
Why ??! Why would they allow that ? So ignorant
I’m calling b******t on this one. In Germany, they don’t use the word police.
Make muslim no go zones, the only zones they can go in. Put a fense around the area and do not let them out.
