A documented history of domestic abuse, we learned this month in the person of former White House staff secretary Rob Porter, does not preclude people from working in the White House. To many, such as Sen. Orrin Hatch (R-Utah) and Chief of Staff John Kelly, it seemed shocking that a well-educated, highly accomplished professional could be violent. But domestic violence is a complicated and pervasive crime (45 percent more women were slain by a current or former male partner between 2001 and 2012 than there were troops killed in Afghanistan), and it is shrouded in misinformation.

Myth No. 1: Domestic abuse is only physical

Because coverage of domestic violence overwhelmingly focuses on physical abuse — think of the photos, the police reports, the restraining orders — many people have difficulty self-identifying as victims of its verbal and emotional forms. A common line of thought was voiced by a woman who told Britain’s Independent newspaper about a relationship with her teenage boyfriend, “He never physically hit me, so I didn’t think of it as abuse.” A HuffPost essay about a man who would “bang his head against the tiled floor, punch a wall, or say he didn’t deserve to live” as a way to control his girlfriend was titled "I Didn’t Know I Was In An Abusive Relationship, Because My Boyfriend Never Hit Me.”

Besides physical abuse, there can be verbal and sexual abuse, isolation, coercion, stalking, economic control, abuse of trust, threats, intimidation, emotional withholding, property destruction, and harm to pets. “Intimate partner violence exists on a continuum of behaviors,” Cosmopolitan wrote.

Myth No. 2: Men are the only abusers

The language and thinking around this issue (“battered woman syndrome,” for instance) are extraordinarily gendered. A male engineer married to a female physician recounted to the Salt Lake Tribune in 2001 the time he called a domestic violence shelter after one especially brutal beating from his wife. “We’re here to help women,” officials told him. “We don’t know what to say to a man.” One posting on the website of the National Organization for Men Against Sexism is titled "Not a Two-Way street: Men are NOT the victims of what is meant by Domestic Violence and Abuse.” And Skylar Baker-Jordan, a gay essayist based in Chicago, wrote last year: “When my ex-boyfriend assaulted me, I found my friends — particularly my male friends — minimizing the abuse or excusing it as a ‘scuffle’ between boys. When I sought support, they got uncomfortable and told me to ‘man up.’ ”

But according to the Centers for Disease Control and Prevention, 1 in 7 men in the United States have been victims of severe physical violence by an intimate partner, and 29 percent of heterosexual men have experienced rape, physical violence and/or stalking by an intimate partner. For gay men, “the lifetime prevalence of severe physical violence by an intimate partner (e.g., hit with fist or something hard, slammed against something, or beaten)” was 16.4 percent, the CDC says.

In 2008, it took four battered men and a lawsuit by the National Coalition for Men for the California courts to recognize that men are entitled to equal protection and advocacy support from domestic violence shelters. A different breakthrough happened in 2015, when the nation’s first domestic violence shelter for men opened in Arkansas. As Prince George’s County, Md., State’s Attorney Angela Alsobrooks told me: “It’s just amazing the number of male victims we have had in the last couple of years, including two run over by their wives.”

Myth No. 3: Domestic abuse is a crime of the poor and uneducated

In truth, domestic abuse is what might be called an ecumenical crime, with no regard for age, ethnicity, financial status or educational background. The problem is learned behavior, not pedigree. Abusers carefully control their actions, choosing who and when to abuse; they don’t, for instance, beat up their bosses. Some label it a “Dr. Jekyll and Mr. Hyde” personality — violent at home, charming and thoughtful everywhere else.

Which is why examples of smart and successful abusers abound. Just think of Ike Turner or Chris Brown. Last year, former South Carolina state legislator Chris Corley pleaded guilty to felony domestic violence charges. This month, “7th Heaven” and “Party of Five” actor Jeremy London was arrested in Mississippi and charged with misdemeanor domestic violence.

Myth No. 4: If the victim doesn’t leave, the situation must be tolerable

This is one of the most destructive myths because it diminishes the severity of the abuse and implies that the victim must be comfortable with it. Victims stay in relationships for many reasons, including fear of the abuser (who often threatens harm if they do leave), lack of money, worry about children and lack of transportation. Another, more recent, cause: the threat of deportation. With no reduction in domestic violence reporting from non-Hispanic victims, San Francisco and San Diego recorded declines of 18 percent and 13 percent, respectively, among Hispanics in the first half of 2017, compared with the same period in 2016.

Victims leave and return to a relationship an average of seven times before they leave for good — or are killed. Departure is the most dangerous moment for a victim, because the abuser suddenly faces a loss of control and may lash out. It’s a Hobson’s choice: Stay and possibly die, or leave and possibly die.

Myth No. 5: The abuser just snapped

When Ronald Lee Haskell allegedly killed six members of his ex-wife’s family in Texas in 2014, a childhood friend said, “Haskell must have snapped.”

But domestic violence is not about anger management or an inability to handle stress. Abuse almost always recurs in a cycle, according to Psychology Today, one that’s based largely on demonstrating control. As Natalia Otero, a lawyer and the executive director of D.C. Safe, told me: “One of the oldest myths is that the abuser is out of control. I’ve seen abusers come into court quite eloquent, quite clear about what they know and what they want from their partner and from the system. Violence for them is not a random act — it is a way of controlling a situation.”
