My opinion, and how I have raised my son, the internet isn't necessarily all bad, since it can be a great source for information. What I taught my son is to critically think for yourself and don't trust one source of information. And to look for the bits of truth in different sources and to bring those together to help form your OWN thoughts on a subject. As for social media (FB, Twit, etc.) those are usually cesspools and to tread lightly.
