Charlemagne, do you even know what you are talking about? Sweden has a muslim population of 7.6 percent, England has a muslim population of 5.1 percent and France somewhere between five to ten percent. Your precious Australia has a muslim population of somewhere between 450.000 to 500.000 while Sweden has a muslim population of about the same size. We aren't 'gone'. Even tough I don't approve of the immigration system in Sweden our economy is rising fast (I know that it doesn't look good when you say it like this). We barely got any poverty, free healthcare, 480 days of paid parental leave, I believe it's six weeks of paid vacation, köttbullar, fika, IKEA, ABBA. Suck it.
TL;DR Australia got as many muslims as Sweden do.
