Look at it this way, it's common knowledge that people who watch porn constantly do so because it features things they lust after in real life but can't get (rape, threesomes, real live adult human females with watermelon jugs, etc). So when other people watch tons of porn featuring babies, it's obvious what they lust after. Don't sugar coat it. Shota fans get off on little boys and loli fans get off on little girls. They lust after children.
I don't have a problem with animated child porn. There are no actual children involved and if it keeps the people who like that sort of thing occupied, all the better. Girls who like yaoi aren't going to go around raping guys with strap-ons, so I doubt our loli fans are going to be attacking little girls any time soon. As long as they label their vids with the proper warnings, people who don't like it don't have to watch it.
Note: Loveless is adult/teenager, not quite as disturbing as adult/baby pairings. I don't particularly like Loveless, but I draw a line at teenagers. I figure if they're old enough to make babies, at least they're physically mature enough for sex which puts it way above most child porn.
