I don't think any sane person would make a claim like that. The issue is the imbalance. I do not believe humanity is incapable of making some cultural adjustments that would benefit the mental health of a lot of people.
That cat is out of the bag. Are we going to return to putting skirts on table legs, high necklines and women's clothes that reach to the floor, to Victorian mores (at least as they were among 'polite' society, in the open)?
We've been assured by the shrinks that THAT created all sorts of problems, now we're going to be told it was the other way?
There is a happy medium, a standard of behaviour which we can find acceptable, which falls far short of the bar set by those who take a well stated and polite compliment and run to HR screaming of sexual harassment, where as a society we can accommodate the behaviour of high and low without resorting to the Burkha and honor killings.
How about we simply ask people to behave, say early '60s standards?
Not sure how that will work with a smartphone 'tinder' culture swiping left and right looking for hookups, or the blatant promiscuity all over the teevee, but if you want to establish new standards of how to behave respectfully toward one another, I'd suggest you begin with the entertainment industry. Not just in how they treat the hired help, but the stuff they put out which establishes the conceptualizations of 'normal' behaviour in many who watch that dreck. As the expectations enshrined in sitcoms and drama become less, so has our behaviour toward one another. THat's something that goes far beyond whistles and catcalls.
