I'd rather see a day's display of Islamic art, food and culture (which all of us can enjoy and partake of) than a token adopting of religious dress. It encourages & perpetuates the co-opting of religious dress like the hijab and burkha as a *political* statement rather than as a genuinely religious one. While I see the reasoning, I also tend to think 9/11 isn't a good day to be making political statements like this, as it could end up causing greater rifts between activists and ordinary Americans.
