There is a lot of evidence that women engage in "slut-shaming" much more than men. It isn't that women are concerned about modesty, rather, women don't like the competition. Women form groups to ostracize and bully "outsider" women, and "modesty shaming" is one way to accomplish that goal.
If traditionalist women were really interested in following ancient norms, then traditionalist women would encourage men to wrap their hands in clothes to avoid touching female skin. In fact, this was arguably one of the reasons both sexes wore gloves whenever they appeared in public.
Despite the fact that gloves were, for centuries, considered an essential part of a public wardrobe, I have never heard a "modesty" warrior argue that glove-less women are dressed immodestly. Which makes me think this isn't about "modesty", it is actually about females using "virtue-signalling" to crush the female opponents in the competition for snagging and holding onto a mate. That is, the women are not actually interested in modesty, rather, they are interested in signalling how good they are, and how trashy their opponents are.
Do I need to point out that this is not a Christian motivation?
Yes, I probably do.
Which is why this follow-up to my earlier post on the correct Christian attitude is necesssary.
