This is what always happens when people start to bring up the tough questions.  There are those who don't like them, don't understand them, or don't care.  So they play word games to shoot you down.

What's happening with this generation is different (and more scary) than past generations, because there's a breakdown of basic societal norms, like family, community, etc.  Combine this with the allure of technology and anybody should be scared.  But nothing will get solved if people run from the tougher question. 

Personally, I'm surprised you never hear anyone mention teens shouldn't even be on social media, especially younger ones or middle schoolers.  They have no context in which to put their interactions, and the more they interact online, the more isolated they become in real life.  I've seen this several times.
