There are many more muslim habits that I'd love to see prohibited. Such as halal meat. I mean, it's all fine and well what they do in their own countries, but here in the West we've got animal rights and letting animals bleed to death without anesthesia clearly violates those
One of the basic characteristics of discrimination is unequal rights for different people, so allowing muslims to violate animal rights, while the rest of us must comply, is simply discriminating our own population/culture in favour of immigrants
PS: I'm not for discrimination, on the contrary, I think everyone should have the same rights, but those same rights count for muslims as well!
