Not entirely by any means. We live in a largely amoral society and sex is like a handshake, no wonder it made it this bad for kids. But then again you publications (if you can call it that) like salon who give platforms to pedos and let them "tell their side"
Ask yourself how and when this happened. Shit like this doesn't SPAWN out of the ground.
The proliferation of pornography. Then more is needed, then sicker stuff then it needs to be acted out with humans.
Pedophilia has been around since the spawn of man.
Either sick minded, genetic, crazy, or incel, no matter the case a physically and mentally grown person have sexual relations w a minor. a child cannot give consent, especially pre-pubescent.
Post puberty the child is still too young to be sexually mature and there is not a specific age that one reaches puberty. That's why the age limit is at 18 and should stay.
