  Why is distrust (e.g. of medical expertise) now flourishing online despite
the surge in mitigation schemes being implemented? We analyze the changing
discourse in the Facebook ecosystem of approximately 100 million users who
pre-pandemic were focused on (dis)trust of vaccines. We find that
post-pandemic, their discourse strongly entangles multiple non-vaccine topics
and geographic scales both within and across communities. This gives the
current distrust ecosystem a unique system-level resistance to mitigations that
target a specific topic and geographic scale -- which is the case of many
current schemes due to their funding focus, e.g. local health not national
elections. Backed up by detailed numerical simulations, our results reveal the
following counterintuitive solutions for implementing more effective mitigation
schemes at scale: shift to 'glocal' messaging by (1) blending particular sets
of distinct topics (e.g. combine messaging about specific diseases with climate
change) and (2) blending geographic scales.
