Kohn: People need to set aside their biases about who commits crime

(CNN) Police in Pennsylvania are investigating the Delta Kappa Rho fraternity at Penn State University regarding two private group Facebook pages where members of the fraternity allegedly posted pictures of naked or partially dressed women, some of whom appeared to be passed out or asleep, "or in other sexual or embarrassing positions." Many of these pictures, it appears — though hopefully it goes without saying — were posted without these women's consent, or even awareness the photos were being taken. The Facebook pages also included pictures of frat members engaged in drug deals and hazing rituals.

This comes on the heels of members of a University of Oklahoma fraternity being caught on video singing an explicitly racist chant. In 2013, the Sigma Phi Epsilon chapter at the University of Texas at Arlington was shut down after three separate incidents of rape were reported to have taken place in the frat house. In 2010, members of a fraternity at Yale marched past a female dormitory chanting , "No means yes, yes means anal!"

Most, though certainly not all, of these fraternity members are young white men. To be clear, the identity of the students involved in the Delta Kappa Rho Facebook posts has not been made public, but 73% of students at Penn State University are white and since Delta Kappa Rho is not a historically black fraternity, it's safe to assume that the Penn State frat is at least as white as the student body, which is to say predominantly so.

These incidents and more remind us of the rampant but often-ignored danger posed by young white men in America today. Although the news media and popular culture constantly cast suspicion on young Muslim and African-American men and the supposedly disproportionate and ever-present threats these communities pose, the fact is young white men are just as dangerous. But because our biases have us so busy looking the other way, we're ignoring the magnitude of this reality.

Certainly not all those perpetrating or advocating sexual and racial assault, within fraternities and outside of them, are young white men. Several of the instances of rape and sexual assault made public recently have certainly also included black and Latino young men. But while studies show that men who join fraternities are 300% more likely to rape, it's simply too easy to blame fraternities alone.
