Because Muslims hate each other as much as they hate everybody else, and make less money than the Mafia. You might as well ask why the Mafia doesn't join a local gang.
They do leave quite a mess with less risk of injury than other projectiles. We should have thought of that back in the 60s!
Nah, our wealthy import Muslims just to give the right wing a hard time. Both Muslims and Christians are often fans of the Nazis and entrenched wealth, so they make good neighbors. Blowing each other up and shooting each other is just good policy when you know only the strong survive because God was on their side, and they both hate Jews more than each other. Its easier to get loans for such things when the Jews know the two will be killing each other. Curly Joe was always the most creative of the Three Stooges, and killing each other is great for stimulating the legal system with lots of cash. A religion that doesn't make money is UnAmerican.
Milkshakes are an islamic thing? Or if they don't throw milkshakes at Farage the door is set wide open for extremist muslims? I have the feeling your comment is supposed to be witty but...
