The world’s wrath and revulsion seem to be focused on Bill Cosby these days, as he goes in the public mind from “America’s Dad” to an unofficial serial rape suspect.

Yet that’s a cop-out for all of us. Whatever the truth of the accusations against Cosby . a wave of women have now stepped forward and said he drugged and raped them (mostly decades ago), but his lawyer denies the allegations . it’s too easy for us to see this narrowly as a Cosby scandal of celebrity, power and sex. The larger problem is a culture that enables rape. The larger problem is us.

We collectively are still too passive about sexual violence in our midst, too willing to make excuses, too inclined to perceive shame in being raped. These are attitudes that facilitate violence by creating a protective blanket of silence and impunity. In that sense, we are all enablers.

The revelation of an alleged gang rape at a University of Virginia fraternity by Rolling Stone underscores how thin our veneer of civilization sometimes is. The article, whose account is unconfirmed, describes an 18-year-old freshman at the university who goes to her first frat party and is led upstairs by her date, pinned down, beaten and punched, and raped by seven men.

Administration policy makes matters even worse. A dean acknowledged in an interview with student-run media that even students at the university who admit to sexual assault invariably avoid expulsion, and that no student had been expelled for rape in years. The student’s report pointed out that the University of Virginia treats cheating more seriously than rape.

The problem once more isn’t just one university, but the broader culture. It’s ubiquitous. This month an inspector-general report in New Orleans revealed that only 14 percent of sexual assault cases referred to the special victims unit there were even investigated. A 2-year-old was treated in a hospital emergency room for a sexual assault and had a sexually transmitted disease, yet detectives closed the case without an investigation.

Meanwhile, prison rape, mostly of men and boys, is too often treated as a joke rather than an appalling human rights abuse. A Justice Department report last year found that in juvenile detention centers, almost 1 youth in 10 had been sexually abused in the course of a single year. At two juvenile centers, the rate of abuse was 30 percent or more.

Then there’s sex trafficking. Ernie Allen, the former president of the National Center for Missing and Exploited Children, estimates that 100,000 children in the United States are trafficked into the sex trade annually. Police and prosecutors often respond by arresting the victims . the kids . rather than the pimps and the johns.

Too often boys are socialized to see women and girls as baubles, as playthings. The upshot is that rapists can be stunningly clueless, somehow unaware that they have committed a crime or even a faux pas. The Rolling Stone article describes how the rape victim at the University of Virginia, two weeks after the incident, ran into her principal assailant.

“Are you ignoring me?” he blithely asked. “I wanted to thank you for the other night. I had a great time.”Likewise, a university student shared with me a letter her ex-boyfriend wrote her after brutally raping her in her dorm room. He apologized for overpowering her, suggested that she should be flattered and proposed that they get back together. Huh?Granted, humans are infinitely complex, and consent and coercion represent two poles on a continuum that can fade into grays. We shouldn’t short-circuit the rights of men accused of misconduct, and frustratingly often it may be impossible to attain certainty beyond a reasonable doubt.

Yet let’s be real. The dominant problem is not an epidemic of men falsely accused of rape, but of women who endure sexual violence . including about one female college student in five, according to the White House.

One study published in 2002 found that about 90 percent of college rapes were committed by a tiny number of serial rapists.

So bravo to those speaking up, male and female alike. In Norman, Okla., high school students say that a male student raped several girls and distributed a pornographic video of one of them. Frustrated by what they saw as administration passivity, the students have been waging protests to educate school officials about right and wrong.

Sure, sexual violence may be embedded in parts of American culture, but, in my lifetime, we’ve changed other cultural norms. Drunken driving is no longer comical or silly, but repugnant. What will it take to get a serious response to all accusations of rape?
