Michelle Obama could have visited a school in Marseilles or Brussels and it would have been the same thing. I'm afraid muslims are all over Europe, bringing in their clothing, their food and their values. The worst being that if you complain about it, many will say you're a racist.
I don't really care about it as long as their religion is not shoved inside my face, or their clothing. The food being shoved might be considerable if it is good, though.
In all seriousness, I don't have problems with anybody living in my country as long as they practice peace. In the end, the rich and the poor are all searching for a little peace of mind.
