Not necessarily. Exactly what is kiddie porn? For starters, if someone uses a hidden camera to photograph or videotape a kid taking a bath, then that can't possibly cause any physical or emotional harm to the kid, because the camera does not physically act on the kid in any observable way, and the kid is not aware of it. Next, even if the kid is aware of the camera, she may not care and may forget about it. Going further, if the grown-up tells the kid to wear some "sexy" outfit and to pose in a certain way, the kid may be persuaded that it's just a silly little game. (Note that kids are already put through unpleasant or painful experiences against their will when, for example, told to sit still while the doctor swabs their arm and gives them a shot, or told to eat "healthy" foods they dislike. If you think any of the above causes serious emotional harm, then you should be gasping with rage when you see most doctors and parents.) This wide range of pictures would probably all be classified as child pornography.

Perhaps you'll say, "What I meant was brutally raping a child and videotaping that!" Well, unfortunately, that's not what the laws cover, and, unfortunately, the laws are what we're talking about. Whether a child was injured in the creation of the media is not mentioned in the laws governing child pornography.

Furthermore, even in the brutal-rape case, the child is not harmed when a third party makes copies of the video. Or even when the rapist makes copies of the video. ...I mean, jesus freaking christ, I agree with punishing the rapist, but the crime is not "possessing videotapes of a child", or even "videotaping a child", the crime is "brutally raping a child"! Grr, the mind-boggling wrongness of it all is making me mad.

Anyway. The poster I was responding to was objecting to virtual child porn--that which is created by an artist and involves no actual children. (So, actually, your objection is completely irrelevant, although it is relevant to the more general argument, so I responded to it anyway.) He seemed to be arguing that the act of watching (or looking at or otherwise consuming) child porn--unrelated to its production--to aid in the construction of a pedophile's fantasy scenario was a bad thing, because it's bad to fantasize about horrible insane things--and would probably say that, therefore, the possession of child pornography (virtual or otherwise) should be illegal, because people who consume it are dangers to society.

I emphatically objected to the "it's bad to fantasize about horrible insane things, and to create media that aid in such fantasy" on its own terms. I would also object to the "dangerous, therefore possession should be illegal" thing: I might observe that people who read the Communist Manifesto are more likely to commit acts of terrorism as a result, or that husbands who drink alcohol are more likely to beat their wives as a result, but I would oppose anyone who tried to ban any of the above.

If this is the case they why has there not ever been a single case of this happening?

I googled [teenagers sexting sex offender]. http://www.google.com/search?client=safari&rls=en&q=... I don't think any of the following explicitly say "recordings of consensual sex", naked or semi-naked pictures of one person by herself being much more common, but surely the former is at least as obscene as the latter, so I think these count. The top several results (excluding a pdf):

http://articles.cnn.com/2009-04-07/justice/sexting.busts_1_p... -> "Phillip Alpert found out the hard way. He had just turned 18 when he sent a naked photo of his 16-year-old girlfriend, a photo she had taken and sent him, to dozens of her friends and family after an argument. [...] Alpert was arrested and charged with sending child pornography, a felony to which he pleaded no contest but was later convicted. He was sentenced to five years probation and required by Florida law to register as a sex offender."

http://www.foxnews.com/politics/2012/03/05/in-effort-to-curb... -> "Some states have classified teens as sex offenders and even charged them with child pornography, all in a well-intentioned effort to save kids from their own bad behavior."

http://www.thedailyaztec.com/2011/03/‘sexting’-gets-teens-on... -> I can't tell if its "17-year-old girl" is hypothetical or merely anonymous, but it says "you would never think for a second this naïve teenager and this heinous pedophile would ever have anything in common. However, as soon as the girl engaged in a process commonly known today as “sexting,” she risked facing catastrophic legal consequences similar to those of pedophiles and rapists. Two words: child pornography." And the headline is "'Sexting' gets teens on sex offender registry".

http://www.usnews.com/education/blogs/high-school-notes/2012... -> does not give a specific example, but "Should those teens oblige, both the sender and the receiver could face serious consequences. Those private photos could resurface online or even land the teens on a sex offender list."

http://www.cbsnews.com/8301-504083_162-20001082-504083.html -> headline ""Sexting" Teens Are Being Labeled Sex Offenders, Lawmakers Look to Change That", says "Nebraska, Utah and Vermont have already reduced penalties for teenagers who engage in sexting, and 14 other states are considering measures that would treat sexting minors differently from adult pornographers, according to the National Conference of State Legislatures."
