How do you explain the entire state of South Carolina found no difference in Covid infection rates for school districts that masked vs. those that didn't? (Per Melanie Barton.) How do you explain no difference in infection rates between Chatham County (which required masking) and Effingham County (which didn't) in Georgia? How do you explain no difference in infection rates between my oldest son's school (which required masking) and my youngest son's (which didn't)?
I've asked you those questions repeatedly and not once did you answer.
