Immodesty for Social Justice?

Okay, so first things first, read this: Israeli and Palestinian Women Take a Rare Swim.

Since I can safely say that y'all probably didn't read it (I know, we all lead busy lives), here's the gist: in an act of civil disobedience, several Israeli women took several Palestinian women to the beach. Which is illegal. Palestinians are not allowed out of the West Bank/Palestine/whatever-you-want-to-call-it. (Have you noticed that what you call that location is making a political statement?) Anyway, here's the part that interests me most. In order to participate, the Palestinian women dressed like Israeli women, which meant wearing significantly less clothing than what they believe is right.

So here's my question. For those of you who do wear clothes that you believe are important (or necessary) religiously or morally, would you participate in something like this, for a cause you believed was right, if it meant shedding the clothes that you believe are right?
