People communicating openly and freely over the internet doesn't seem like much of a problem to me. The one thing he does get right IMO is that if you want to make real progress on this stuff you have to dig into root causes. The fact that people are rightfully distrustful of institutions isn't Facebook's fault and. It can't be solved by censoring Facebook.

This is an oversimplification. Communication is the foundation for nearly 100% of all events - good, evil, and neutral. It doesn't make sense to just call it good or bad as part of an argument.
I think we can all agree that we have a social media problem.
