Congresswoman Katie Hill’s sexual relationship with a much younger intern is a classic “MeToo” situation, and on Sunday, she belatedly realized the gravity of her offense and now plans to resign.

But it shouldn’t have taken so long — more than a week during which she was aggressively buttressed by hypocritical defenders on the left.

By claiming that Hill was the victim of a political smear, she and her supporters showed no concern for the vulnerable 22-year-old who was preyed upon by her boss and who now, two years later, is bereft, abandoned and a self-described “mess.”

The same people who demonize males for far less gave Hill a free pass for her egregious abuse of power.

The Guardian even helpfully has explained the ethical distinction between men and women committing the same offense: “When Hill engaged in an affair with a campaign aide, she did not do so in the context of millennia of men’s sexual violence against women.”

Seriously? This despicable sophistry undermines everything the “MeToo” movement is meant to be about.

It shouldn’t need to be said, but in a world with so many moral compasses gone awry, it seems necessary to point out that when a member of Congress has a sexual relationship with a staffer, particularly one who is a decade younger and fresh out of college, that is an abuse of power.

To spell it out, if your boss is having sex with you, something is wrong. The power imbalance undermines the notion of consent, regardless of the gender or sexuality of the more powerful person.

The House Ethics Committee is investigating Hill’s behavior, including allegations of another affair with a male staffer, which she denies, to see if it violates congressional rules.

But whether it is or isn’t technically a violation, it’s still wrong by any standard of basic human decency. And you can bet that if Hill, 32, were a man and, God forbid, a Republican, the “MeToo” crowd would show no mercy.

No man could get away with describing a sexual relationship with a subordinate whose paycheck he controls as merely “inappropriate.”

Hill, described by Elle magazine as “one of the most powerful” freshmen in Congress, and a protégé of her California stablemate Nancy Pelosi, wielded power every bit as potent as any man.

What makes this situation worse is that she prevailed upon her susceptible young staffer Morgan Desjardins to enter an emotionally perilous “throuple” relationship, or sexual threesome, which included Hill’s husband, Kenny Heslep.

After a week of bombshell revelations, taken from divorce documents filed in July by Heslep and published by the conservative blog Red State, Hill sent a letter blaming everyone but herself to her California constituents — who must be thrilled at the antics conducted in their names.

“I am going through a divorce from an abusive husband who seems determined to try to humiliate me,” she wrote. “I am disgusted that my opponents would seek to exploit such a private matter for political gain … I, like many women who have faced attacks like this before, am stronger than those who want me to be afraid.”

Sorry, but when you conduct your private life in such an exploitative and hypocritical fashion, you don’t get to play the victim feminism card.

It’s no surprise to learn the “throupling” ended in tears. That much is clear from even a cursory glance at texts among the threesome published by the Daily Mail in an exposé that included pixilated nude photos of Hill.

In one of the photographs, a naked Hill is sitting behind the fully dressed young intern, brushing her hair in a sick facsimile of maternal tenderness. In another, Hill is holding a bong.

Her defenders have cited the photographs in order to cast her as a victim of “revenge porn.”

But the real victim emerges more pitifully in heartbreaking text messages sent to Heslep in June, in which the young campaign staffer allegedly describes their threesome as “toxic.”

“I’m still a mess over you ­f–kers. I didn’t realize how much being the dirty little secret bothered me …

“It was a dark time and you treated me really poorly but I also stayed which I have to own.”

And later, “I am still in love with her. It rips my heart out every time I have to see her … She doesn’t care or really have any concept of how deep the wounds go.”

At face value, the messages appear to depict an abusive, exploitative relationship. However, as part of an ugly divorce, it’s only fair to take them with a grain of salt.

Hill is innocent until proven guilty. But, of course, that is a right she did not afford Justice Brett Kavanaugh when she was branding him a “serial predator.”

Projection, much?

The ‘End’ of Women

Slowly but surely, women are being erased.

Democrats demand abortion rights for men, doctors treat pregnant “people,” female athletes have to move aside as biological males win all the trophies.

Now Procter & Gamble has erased women from sanitary pads, too, under the delusion that men can have periods.

After pressure from transgender activists, it will remove the female circle-and-cross symbol from its Always sanitary products.

“For over 35 years Always has championed girls and women … We’re also committed to diversity & inclusion.”

How dare some woke company disrespect the shared experience of every woman in the world?

There is nothing so profoundly womanly as menstruation. A girl becomes a woman when she has her first period. Not for nothing is it called “the curse,” but it’s our burden and central to our fertility.

The tiny minority of people who suffer because they feel they have been born into the wrong body deserve compassion and respect. But they don’t get to delete womanhood.

Alice Cooper had it right: Only women bleed.

Never forget victims of ISIS

Good riddance to Abu Bakr al-Baghdadi, the ISIS leader killed by US special forces. But rather than reveling in triumphalism over his death, we should remember the victims of his sadistic caliphate.

The president mentioned James Foley, Steven Sotloff, Peter Kassig, Kayla Mueller, but there also are more than 1,200 innocents murdered in ISIS-inspired terror attacks around the world — and an estimated 20,000 civilians killed in Iraq.

The leader may be dead, but his Islamist ideology lives on.

Lawless Dems

“There oughta be a law,” said Gov. Andrew Cuomo about serial subway fiends.

Well, there are plenty of laws, but Cuomo and his Democratic lawmakers are turning the courts into revolving doors of leniency while emasculating the NYPD.

It’s only going to get worse on Jan. 1, when more of their criminal justice “reforms” go into effect.
