It's either an upswing of stupidity, or people are just noticing it/making a big deal out of it more.
I remember Mom telling me that when girls got pregnant when she went to school, they would go to "live with an aunt" for awhile (about 9 months.......) give birth, give the kid up for adoption, and go back to school. They just... wouldn't talk about it at all.
Same thing with kids getting kidnapped. It happened with alarming frequency, but no one talked about it, because it was "disrespectful" or some other bullshit. I got the impression that they were just trying to pretend that everything was hunky dory.
Nowadays, people talk about it. It's getting in the news. People are making big deals out of it for good or ill. If anything, the fact that we are hearing about this more may not be a bad thing. A bad thing would be if this stuff goes on all the time and never gets talked about. A good thing is when it becomes controversy and people talk about it, because it means that our society, as a whole, is improving.
...What's not an improvement is that gossip and rumormongering are also more common and more damaging now, thanks to the power of the internet.
