Marco,
People in the West wear what they want (including hijab) because they are supposed to be free. In Qatar they make no such claims of freedom so people observe a dress code.

It seems that people like you, who want to introduce dress codes in the West, are trying to be more like those in the Middle East.

Make up your mind Marco, you can't have it both ways, either you support freedom and live in the West or you support bigotry and live in the ME. Did you come to Qatar so that you could be with like minded people?
