exactly that but less so "extremist" more so "common".
We've managed to forget about what the "common" sort of opinion is like. An opinion poll about the death penalty or immigration is a quick way of seeing that society at large is somewhat detached from what people assume is the "norm" from the world of edited media circa 1990 - 2010.
When the internet exploded that "average" was still glued to the TV and nerdy wasn't cool. Even in the 2000s you still had to run a PC to attach which is still a bar to hurdle.
Today though we now have a generation that has grown up with internet enabled devices as a default feature in their phones, consoles, TVs or other formally "dumb" boxes. Now _everyone_ is online and perhaps that is just what we're seeing here as the bar for internet access has completely vanished.
