> Immigration doesn't help. Swimming isn't really something people do in Iraq or Afghanistan. And boys and girls can't swim in mixed groups.
? It is completly irrelevant, the proportion it represent is next to none.
For your reference
> The largest group of immigrants and their descendants in Belgium are Italians, with more than 450,000 people, which is well over 4% of Belgium's total population. The Moroccans are the third-largest group, and the largest Muslim ethnic group, numbering 220,000. The rest consists mostly of French-speaking people from Brussels, Turks, Kurds, Dutch, French, Portuguese, Spaniards, Greeks, Bosniaks, Algerians, Congolese, Vietnamese, Poles, Indians, and Guineans (around 23% of Belgium's population is of non-Belgian origin).
Moroccan people swim just fine.
I really do wonder how can people have that idea on their mind at all time even in cases like this where it doesn't even begin to be in scope.
