If you're asserting that anxiety around vaccines is not inspired by some guff that originated on QAnon or similar, then I disagree.
All of the hesitancy over vaccines is the result of overt and covert opinion manipulation. All of the receptivity comes from dishonest thinking and, frankly, sheer ignorance of statistics and of how vaccines are developed, tested, and authorised for use.
It's a heady mixture, where scientific ignorance builds on whispers of attractively simple answers to complicated questions all over the internet and, sadly, all over politics, because some politicians are utter charlatans. You seriously underestimate the attractiveness of simple answers for a great number of people.
All this nervousness all over the internet has its origin in the multiple internet and political voices whose aim is the discrediting of all sources of authority, including medical and scientific, but also political and legal, that constitute the foundations of society.
Again, there is no obligation on the part of MN or any other site to host any of this.
