I did read the article (by Rabbi Leib Kellman). And it is a point that I have heard many years ago. The men have no clue what is and isn’t allowable and therefore women do as they wish. The women have been taught better, but when their husbands say “nice skirt” without realizing how many problems there are with it, then she will wear it. If the men know, they will be able to speak up with confidence. And if the women know that their husbands know they won’t be able to whitewash that which is wrong.
As to the girls – teenage girls can be really sensitive. If a mother is inclined to “let this one go” on a questionable garment, but her husband tells her not to – then she won’t and will be stronger with herself and her daughter.
The emphasis today on looks which starts with shidduchim (which starts at about bas mitzvah age!!) exacerbates this problem. Blazers aren’t “stylish” so why would a girl want to wear one when a fitted sweater is more “in” and makes her look “nicer.” The spirit of the law gets completely lost in all this, and it isn’t far until actual halacha is breached.
As to the other areas that were mentioned – such as hilchos shabbos and kashrus, I think most men are at least as aware as the average BY graduate. The difference there, is that girls are taught to know to ask, not necessarily what the halacha is in every situation. Boys are taught more halacha l’maaseh and don’t realize how many holes there are in what they have been taught. (And article like the one in the previous week’s Ami don’t help!)
