Sometimes, Oz Vehadar Levusha quotes sources that don’t clearly support what the sefer claims that they do. For example, the Gemara in Pesachim teaches that the Torah doesn’t mention the word “merkav” in connection with a zavah because it is indelicate to refer to a woman riding an animal in a straddled position under normal circumstances. This is because under normal circumstances it is only considered modest to ride sidesaddled. However, the gemara teaches that in cases where circumstances require even modest woman to ride straddled, such as when riding with children or riding on a mountainous trail or riding on a camel, it is fine to mention that they were riding straddled on the animal. The upshot of the gemara is that it is not lashon nekiya to reference behavior that is less than perfectly tzniyus. Derech agav, we see that it is considered untziyus for a woman to ride an animal straddled if she doesn’t have a reason to do so.
This is the source that Oz Vehadar Levusha uses for saying that it is assur for women to wear pants. It is one thing to assur women wearing pants, but it is another to cite a source that is tangentially relevant at best.
This was just an example, but there are a lot of things that the sefer tries to assur that are not properly supported. Like video conferencing, for example. I can understand some people wanting to assur it, but saying that it is unequivocally assur is a ridiculous stretch.
Five years ago, my Rosh Yeshiva told me that he was sent a copy of the sefer by the author for review. My RY had about 400 “he’aros” on the sefer, many of which were arguments against different things written in the sefer. The author responded that he hoped to address many of those points in a later edition of Oz Vehadar Levusha. Does anyone know if a new edition has been published since then?
