One more thing to point out.
The common notion of Tznius is a misrepresentation of Daas Chachamim. Anywhere that the Gemara discusses what we call today Tznius, the Gemara refers to it as Kavod.
It is almost a lost sensitivity. However, people invoke כל כבודה as if it is a sentence being imposed — but for your own good. But the whole point of that verse is exactly about honor.
Picture an actual princess of old. If she is only seen from time to time there is a special respect everyone would have in her presence. But once you begin seeing her in the market every day, there is only so long that you can maintain that special attitude.
This has clearly happened in the last 100 years, or so. Men used to act more refined when in the company of women, especially non-relatives. There is still a remnant of this, that seem almost arbitrary by now. But mostly, it is gone.
You can’t turn back the clock, but you can try to capture what was veing conveyed by these descriptions of refinement. And perhaps we can still grasp on to some of it, maintain what is possible, adapt what can be adapted, and learn from the rest.
Women have indeed been mistreated in many places, in many ages. This lead to a counter reaction and an unhealthy jealousy, and a desire to act fully like men, rather than to gain their own respect. But to the outside observer, the honor and respect that had been there is gone.
What is really gained by drilling in the street? How does faking macho stuff make you proud? What’s the big idea? It’s as silly as men showing off that they can cry and hug a bear.
My bottom line is that these Maamarim are indeed advice for respect, and not sentences. If society has lost the desire for the respect, and people are interested, I don’t see the point in bringing it up. But it is a mess.
