Are you doubting the data, or just reminding us all that generalizing is prejudiced.
I hate generalizations.
The study left out things I would also consider important though. What is the comparison on STD’s in bisexual, lesbian and hetero women? The assault statistic, is that more likely to commit assault on their partner or on other people? What is the incidence of date rape in lesbian and bi-sexual relationships as opposed to hetero relationships?
Also, when I would go out dancing, most girls I knew in the clubs were in their early 20’s and were experimenting with many things at that time, booze, cigarettes, and same sex relationships. Thy self-identified as bi sexual at that time period even though they were as my mother would say “Just going through a phase”.
And what constitutes bi-sexuality in this survey? A 16-year old girl who kissed another girl at a party may label herself as bi-sexual because teen guys think “that’s hot”, even though she’s not into women.
