It's worse than the Eternal September. It's definitely more toxic than it's ever been, and people are definitely more polarized. The 2016 election news cycle got a lot of otherwise normal people really radicalized and hostile. Sure most of the old-timers among us remember, often fondly, the constructive insanity of usenet. And the younger generation remembers the torrent of pure id that was 4chan in the early days, and 8chan later.

Here's the thing. It's leaking. This stuff used to be contained, kept in a little secret segmented-off piece of your world that was 'the internet'. Now it's invading your real life, your real-world friendships, your workplace, even your family.

Think of the Greater Internet F-ckwad Theory: "Normal Person + Anonymity + an Audience => Total F-ckwad". Now run that function over the entire populace, map/reduce style. Now take that F-ckwad, and remove the Anonymity by requiring them to use their real name. And bingo, now you live in Interesting Times.
