I agree that there are problems with Matisyahu's very commercial Chanukah video. Read the comments on my Shiloh Musings posting. For sure the female could have been dressed modestly, according to the norms of tzniyut.
I've been in Israel forty years, almost exactly if you count the months two-thirds of my life, but I haven't been able to totally delete my earliest years. Because of this my perspective isn't what you'd generally expect from the way I dress. We're judged by our "uniforms." Yes, we're all in uniforms, because clothing is like publicizing a membership card. Of course, we can change our clothes and change our image, impression on others.
Chazal, our Sages, say that in Biblical times, when the single girls danced in the Valley of Shiloh, they exchanged clothes, so that they didn't wear their own white dresses. A rich girl could be in a simple, inexpensive dress while the poverty-stricken girl could be in the dress of a wealthy girl. Our clothing is external, superficial.
Because of this, we all must be so careful how we speak to others, because we may accidently say something offensive. One of my pet peeves is when someone giving a shiur Torah Class prefaces something by saying:
"כמו שכולנו למדנו בגן"Well, I didn't go to gan, nursery school, and if I had I wouldn't have learned any Torah stories there. Though born Jewish and raised in Jewish neighborhoods, Torah wasn't on the menu, not in the curriculum.
"Kimo shekulanu lamadnu b'gan..."
"Just like we all learned in nursery school..."
The first time I heard that expression, it was from a distinguished guest rabbi. I sat fuming, because I felt totally left-out, rejected. By his saying those words he excluded me from the group. I was dressed like the other women and understand enough Hebrew to attend Hebrew-language shiurim, so he simplistically took for granted that we in the audience were "all the same."
I didn't feel right getting up and walking out, nor did I think it good form to interrupt him and tell him how he had insulted me. About a year or so after that experience, one of my neighbors gave a class to us and used the expression. Knowing that he would never intentionally or unintentionally hurt me, I politely interrupted him and told him how I felt. I also mentioned that I wasn't the only one in the group who hadn't gone to gan. Some of the women were from even less Jewish backgrounds and even converted to Judaism. You can't tell by looking at us. Since then, he is much more sensitive to the issue.
Should I have spoken to that guest-rabbi? I'll always wonder.
