In this example it sounds like there are multiple sides, just that one is baseless. Even these though I have found come from somewhere, maybe a misunderstanding or a conflation of unrelated topics. While not unlikely intentional on the author's side, the readers are not so sinister I think. Being able to read this while grounded with the other more factual side helps when discussing with those I may otherwise generally disagree with. It has felt somewhat like language learning, understanding it helps with communication with people with a very different background.

Admittedly it takes more time to do this, and I can see not being able to invest that in a general sense. I personally think it's worth it.
