This seems like an odd statement, since "dysfunctional" can only be defined in contrast to the majority behavior. It's like the chestnut that 80% of drivers are above average.
I would have used the word "abnormal" if I were to be comparing it to be the majority. Of course the what is defined as dysfunctional would subjective. A bunch of males fighting/competing with each other to death might be heroic in the eyes of some and the behavior can be normal and can be indulged in by the majority, but in my view would be dysfunctional. Guess it a semantics thing?
