The public is sometimes protected from this information, but every year over 1,800 college students die of alcohol-related unintentional injuries. If colleges broadcast deaths, then parents in a panic rush their children off to another school. Bad publicity inflates.
For this reason, some secular schools have chosen to be dry campuses, and enforce it.
The statistics above refer to unintentional injuries; there are also untold numbers of acquaintance rapes on campuses, many associated with alcohol. The issue is not just about how much we drink, but how much our friends drink.
In some ways I agree with her reasoning -- that it's what we do while drinking that is the bigger problem. But some people have no recollection.
I have friends who have been through rehab, lost jobs, lost custody of their kids, died of cirrhosis, lost their license to drive for over a year, and were not able to get auto insurance. Over the years, drinking takes its toll. I have also been to funerals of people who died of alcohol-related causes.
A little drinking is fine. Some cultures drink all day long. But the body and mind lose a little control, and limits are often passed, and people find themselves deeper in trouble than they ever imagined themselves.
