Current Vice President Mike Pence stated publicly that he will not be alone with a woman not his wife, at a meal, a conference, etc. He's receiving something of a hailstorm of criticism from certain feminist quarters as being "sexist" in his attitude. He defends himself as being respectful of his marriage, and not wishing to permit the slightest credence to accusations of temptation or infidelity.
Two points in my mind: first, it's a proper and necessary self-defense necessary to protect oneself against predatory and malicious opportunists who could later make (baseless) accusations. With no witnesses, it's the classic 'he said, she said' case where the accused party stands guilty until proven innocent.
The other point: why is his position so objectionable? It appears the critics want it both ways: they wish to be free to make accusations if a remark, or gesture, or question during an encounter is _perceived_ by them to be improper, harassing, sexist, or provocative; but they also demand that he expose himself to potentially self-entrapping situations, lest it appear that it is indeed, a potentially perilous position.
I'm also taken by the reality that the VP's wife is NOT a slender trophy blonde, but more closely resembles millions of real-life spouses. And he calls her the most beautiful brunette in the world. Fascinating!
In the US, currently, there is no plausible defense against the character assassination of one party accusing another party of sexual aggression. Unless, of course, the accused is sufficiently wealthy, powerful, or celebrated to be held untouchable.
