Literally pedophile means "one who loves children" and the name roots of the name don't mean something unnatural, as a "Japanophile" is someone who loves Japan. But, naturally, this sort of child love is unaccepted in society, so it has come to mean an "unnatural love of children".
I saw those weird videos sold even at 7-11 in Japan. If it was 11-year-olds buying them, I wouldn't have a problem, but grown men buying videos of u-15 girls posing in bikinis and school uniforms in adult and suggestive poses (and don't say "She's just licking a lolipop! What's wrong with that?") need to have their heads examined.
