Yserbius123,
“I watched a room full of people, (including children as young as ten!) daven on Yom Kippur and wear a mask the entire ten hours they were in shul!”
A room full of people when regulations in most states require reduced capacity indoors? How were you ok with that? Also, if the virus is transmitted via aerosols and not just large droplets, the masks would’ve become useless by Yishtabach as breath escaping the increasingly saturated masks became well mixed into the room air.
