I can't believe an ad about hijab is the source of so many contradictory opinions. In my opinion, everybody's free to do whatever he whises, to say whatever he thinks and wear whatever he wants. Simple as that! Only God can judge us all, no man should tell another man how to live his life.
Ah, and by the way, I do wear the hijab. Sometimes I love it and sometimes I hate it because it makes me feel uncomfortable and look older, but wearing it was my own choice, nobody forced me into it and I don't regret it. Oh, and I don't see it as the biggest act of faith that a woman can make, there are other things more important to a muslim woman.
And just have to say that the only thing I liked about this ad is that women are sweet candy and men are flies. lol, no ofense guys!
