I hear you. I used to think I knew where the bottom was, but I was way off.
Thanks to a continued disinformation campaign from the CDC and the World Health Organization, it isn't even "mainstream knowledge" that Covid is airborne by aerosols, that it's removed by HEPA filters, that it's removed by N95 and P100 masks -- thanks to deliberate fraud by the CDC, it isn't even mainstream knowledge that Covid is wildly out of control with extremely high transmission in the US.
"Mainstream knowledge" hasn't left the dark ages.
@BE I hope so, too, but I am not at all confident.
