Teenagers say arguing is normal

The Boston Globe reports:

Of those questioned, ages 12 to 19, 71 percent said that arguing was a normal part of a relationship; 44 percent said fighting was a routine occurrence.

The results of the survey, conducted by the Boston Public Health Commission across the city and equally among boys and girls, are startling for local health workers who see a generation of youths who seem to have grown accustomed, even insensitive, to domestic violence. ...

Health counselors are specifically concerned with teenagers' views of the controversy. Of the teens questioned, more than half said both Brown, 19, and Rihanna, 21, were equally responsible for the assault. More than half said the media were treating Brown unfairly, and 46 percent said Rihanna was responsible for the incident.

So what is so startling? Do the local health workers somehow know whether or not Rihanna is responsible for the incident?
