Child porn is obviously sick as anyone here would agree.
A child being exposed to it is not acceptable either.
Miplank, what if you caught your kids looking at porn? You sure as hell would not just ignore it and let them do it and think there's nothing wrong with it. No fucking way in hell would a sane parent do that.
The curiosity of it is completely normal, no doubt.
As SD said, pornography addiction is a huge problem. Pornography is related to the ever increasing divorce rates, addiction (it becomes psychophysical, not just mental, the body becomes addicted to orgasm through visual stimulation of pornography while being competent removed emotionally from the subject), it alters the chemical reactions in the brain and perception of proper sexuality and decency of the subject, and is what leads to many become exposed to child pornography and becoming abusers themselves because they become visually stimulated by children committing sex acts which many in turn end up acting out this stuff on kids. Had they not been exposed to child pornography, they never would have had a problem. This is all documented scientific research as well.
Don't tell me there's nothing wrong with it. Especially for little children, holy shit.
