From the guy who is really responsible for the Penn State sex abuse scandal, even if he hasn't been charged:
That is the word Graham B. Spanier, the ousted Pennsylvania State University president, chose to use in response to the charge that he knowingly overlooked the crimes of a child predator in his midst. The allegation defies logic, he argued in a July letter to Penn State trustees, because Mr. Spanier has devoted his scholarly and professional life to studying the welfare of children, and is also a victim of [physical, not sexual] abuse....
...Mr. Spanier's defense has prompted renewed focus on his scholarship, as reporters and bloggers scour journal articles and books that had previously been of passing intrigue to few outside of academe. What the publications reveal is a man whose fleeting interests in human sexuality led to a broader and sometimes pessimistic exploration of the state of the American family...
...The article, "Sexualization and Premarital Sexual Behavior," examined several variables, including abuse, that might compel a person to have sex before marriage. The paper served as a retort to critics of formalized sex-education programs, which Mr. Spanier found to have no direct link to premarital sex patterns.
Mr. Spanier concluded that sexual abuse before the age of 12 or 13 would have no influence on premarital sexual behavior, because genital touching would be "interpreted by the child as tickling or playing, whether pleasurable or not."
Mr. Sandusky's victims, who were all boys, ranged in age from 8 to 17, according to prosecutors.
In the context of recent events, Mr. Spanier's assertion that young children might interpret sex acts as "playing" carries a distinct irony. After an assistant football coach saw Mr. Sandusky raping a boy in a Penn State locker room in 2001, Mr. Spanier said he was told only that there had been some "horseplay."
"I didn't conjure up ... anything more than throwing water or snapping towels," Mr. Spanier told ABC.
Young children may not understand sexual experiences, but they know enough not to talk about them, Mr. Spanier surmised in his research.
"Children probably pick up cues from adults about sex play which inform the children that it should be concealed," Mr. Spanier wrote.
Mr. Spanier's 1975 paper only examined sexual abuse in girls, not boys...
There's a lot more at the link. I'd really like to hear noonwitch's take on this.
