I am not defending anything. In fact, I have repeatedly stated that men should NOT look at women, or how they are dressed. They should certainly not be looking into other peoples cars. You stick your head where it doesnt belong, you run the risk of seeing things you might not want to see.
I am not defending women who dress in a way that violates halacha, perhaps you choose to see it that way. I have repeatedly commented about what I see as the foolish perpetuation of the almost obligatory browbeating of women, mostly by men. It accomplishes nothing and any attempt at tochacha (which I doubt is uppermost on most peoples minds but that is another story) is lost with the negativity.
Seriously want to make an impact? Explain to those who sell the objectionable clothing, why they should not. Your friend in shul has a wife or daughter who contributes to this so called crisis, speak to him, or the Rav, or the Rebbetzin, let them deal with it.
Note: To the moderator that did not allow an earlier post through, thank you. I regretted writing it 30 minutes after I did.
