Once again, science and common sense are tossed out and replaced with "Obey or else." Apparently, no one in California, or the CDC, for that matter, remembers the basic physics of fluid dynamics. Fluids, which include gases, are subject to the Venturi effect, in which, in this case, the increased pressure gradient on the inside of the mask from exhalation are expelled through the narrow spaces of the mask fabric, and around the edges as well, at higher velocities. This results in the exhalation and all its contents being driven farther than an unmasked breath, thus increasing chance for a wider area dispersal. There is also some Venturi effect on the inhalation side, as breathing in pulls in more air and all its contents in through the small spaces to fill the inside of the mask like a vacuum cleaner chamber.
WTF?
Exactly
They know that vaxed shedding is real

Move out of CA!!!
