Generally accepted academic studies say one out of every four women was sexually molested by an adult before she was 18.
Actually, no. The "generally accepted" statistic is that 1 in 4 college women have either been raped or suffered attempted rape at some point in their lives. Furthermore, 57% of the women were on dates at the time. Therefore, given the age at which most women begin dating, the odds would seem to indicate that more of the women are 18, near 18, or older than 18.
Also, at least one basis for that statistic was a Cornell University study where the professor (Andrea Parrot) so expanded the definition of "rape" beyond what is considered the legal definition that she rendered the statistic meaningless:
Dr. Andrea Parrot, chair of the Cornell University Coalition Advocating Rape Education and author of Sexual Assault on Campus, begins her date rape prevention manual with the words, "Any sexual intercourse without mutual desire is a form of rape. Anyone who is psychologically or physically pressured into sexual contact on any occasion is as much a victim as the person who is attacked in the streets"
I was a student at Cornell at the time and worked on a journal that covered the professors research. Therefore, I am familiar with the professor and her methodology. That professor called pretty much any sex that wasn't initiated by the woman as "rape," including sex resulting from the man, basically, "begging" the female for sex (ie, a "pity fuck").
