The glue that holds the Muslims together is hate. They haven't contributed one single positive thing to this world,and I think that they must know it. They resent the world because they are primitive superstitious losers who serve no purpose on this planet. Cockroaches have more right to take up space on Planet Earth than they do,at least cockroaches don't want to murder or enslave everyone who's not a cockroach. If the Islamopigs could ever manage to accomplish their goal-to murder everyone until they could take this world into the dark ages with themselves,then they'd begin to eat their own,because if they're breathing,they're killing. I wish the world would get a clue and realise that these people have nothing to live for,can't make anything of their own countries,and resent the outside world for their inferiority complex,and want to just kill us all so they won't have to be shown up for the neanderthals that they are.Actually,neanderthals were advanced compared to them.
they contributed algebra, but that was a very long time ago.
