The toxic binge-drinking culture at American colleges and universities was on display again last week at Penn State University, which has suspended yet another Greek organization after an 18-year-old student was found Sept. 28 unconscious on a street in State College.

It’s just the latest example of why university officials need to follow through on a threat made earlier this year, and permanently abolish Greek life at PSU.

On Feb. 4 19-year-old Timothy Piazza died after falling down a flight of stairs at the Beta Theta Pi fraternity house, during a bid-acceptance ceremony that included heavy drinking. The incident spawned criminal charges against more than a dozen former PSU fraternity brothers.

In response the university banned drinking at Greek functions through spring semester and threatened to abolish Greek life entirely. But the warning apparently didn’t take.

Since the ban nine Greek organizations have violated at least one of the university’s new rules on dealing with alcohol and Greek life. Two Greek organizations, the fraternities Sigma Alpha Mu and Delta Tau Delta, have been suspended.

Delta Tau Delta’s suspension was announced Wednesday in connection with the Sept. 28 incident. The university says the frat’s suspension is on an interim basis while PSU officials complete an investigation.

But the writing on the wall is clear: PSU needs to follow through on its threat and abolish its dysfunctional and dangerous Greek system now.

It’s clear that members of the Greek community at the school aren’t capable of responsibly managing the role alcohol plays in their events. They couldn’t even abide by special rules the university put in place as an exception allowing drinking on parents weekend in April.

After the weekend — which resulted in Sigma Alpha Mu’s two-year suspension from PSU’s campus — university President Eric Barron wrote in an open letter that even some parents were intoxicated at Greek events on campus.

If the poor decision-making skills of some PSU Greek alums needed more showcasing, there’s also an email sent in September to dozens of Beta Theta Pi alumni, declaring the house where Piazza died open for their “exclusive use,” including catered meals and get-togethers in the tap room.

That’s disgraceful and disrespectful, but hardly surprising. The university’s Greek organizations have had years to clean up their act and failed. In 2015 Barron ordered a review of the university’s Greek system after the fraternity Kappa Delta Rho was suspended for posting explicit photos of women to a private Facebook page without the women’s’ knowledge or consent.

It would be ridiculous to draw direct connections between the behavior of dozens of people across different Greek organizations on campus. But taken together the actions of these groups are sending a message that must be heeded.

Piazza’s death is no isolated incident. In the past year students at Stony Brook University in New York, Ferrum College in Virginia, Skidmore College in New York, and Lafayette College in Easton, Pa., have died as a result of excessive drinking.

Something is terribly wrong with Greek life when incidents such as these occur and proliferate, but fail to spark serious changes within organizations that claim to be built on ideals like brotherhood and community service.

Those claims can’t be taken at face value any longer, and PSU would be better served to nip any further incidents in the bud and abolish their Greek system immediately.
