I was molested by my 14 year-old babysitter when I was 6 years old. I never recieved "treatment" for it, and my parents never talked about it, but thankfully my mother did press charges and saw that the son-of-a-bitch was removed from his home where his younger sisters (my age) lived. I can't speak for anyone else, but I know that it affected me in ways I still don't fully grasp. I agree that this is a subject that should perhaps be studied with more scientific scrutiny, but my own experience, and from talking with other women who were also molested as children, confirms my belief in traditional, conservative wisdom regarding childhood sexualty.
Sexuality in humans seems to be a switch that, once flipped, cannot be turned off. My experience was cruel to the extreme, not just because of the incident itself, but because of what it did to my sexuality. That pervert took an innocent 6 year-old who had no conception of sex and turned her into a child who had drives and desires and no idea what they were or how to properly channel them.
The pedophiles are correct-- the children who are molested do not universally hate the experience, and many would tell you that they liked the adult attention. The sex drive in humans, like all animals, is a powerful one, and asking someone to say that they regret being sexualized is like asking someone if they regret the sesation of appetite and hunger that comes from the drive to obtain sustenance. Pedophiles and child molsters are today capitalizing on this truth, and would convince you that it is ok to prematurely sexualize children because the experience is not 100% harmful.
The effects of pre-sexalizing children are long-reaching. Girls who are sexally molested tend to have problems with forming male attachments and are more prone to lesbianism. Boys who are molested are more prone to homosexuality. All children who are molested have some form of sexual disfunction and a lingering sense of guilt.
Conventional, conservative wisdom has always maintained that children should be sheltered from sexuality and sexual experiences so that they can grow to a more mature level before they have to deal with such a powerful drive. In societies where parents are allowed to shelter their children in this manner, there does seem to be a strong indication that this works to keep children from sexualing early. In other words, the pedophiles are wrong that all children are naturally sexual. Children, like all humans, can be sexualized at a young age, but it is not a "natural," immutable force. Children, if not nudged in that direction, can in fact have long childhoods innocent of the sex drive until puberty. This has been a goal of Western Civilization until present. And pedophiles want to change this.
