Joe Rogan is notorious for this, as he vehemently believes every single thing he sees or hears from Twitter as being reflective of the state of the rest of the real world. This is because he, ultimately, is actually sequestered from real society, operating in a tight little bubble of an elite privileged few.
And this is no different from other small, vocal, and ultimately isolated communities of people who spend all day together… Just online.
I live in a suburban part of Southern California, I deal with regular people of all shapes and sizes and ages and races daily basis in person. 99.99% of them have absolutely no idea about any of this nonsense. not a single thing from this article would even register on their personal radars. unless it was served up to them on a platter by which ever partisan news network they happen to check in with once in a while.
and don't even get me started on the fact that the vast majority of this Internet activity is ultimately bots, bored trolls, and paid schills.
also: why is this article focused on modern mass media? Simply look thousands of years ago at the original mass media mind prison called religion.
