In what world did I blame the child? If a kid climbs on a dresser while unattended and the dresser crushes them, you blame the parent, not the dresser.

And since I probably have to spell it out, a rapist would be the equivalent of someone pushing the dresser onto the child, so obviously you would blame the person. But in this hypothetical, Omegle is an inanimate piece of furniture. Any piece of furniture would suffice, the problem is the lack of parental presence and the person crushing the child.
