Buddy, I've been a board-certified practicing physician for almost 20 years, and every doc in America would have told you the same damn thing about masks until April of last year. Remember the illustrious Dr. Fauci telling everyone not to wear them? There is a plethora of research on viral transmission prior to 2020 that shows no benefit using cloth or surgical masks. Have you stopped to wonder why areas and schools without mask mandates are doing EXACTLY THE SAME as areas with such mandates? Have you stopped to consider what happens to people's hands (like basketball coaches) when they rub all over their mask and pull it down to scream? This takes some critical thinking, which may interrupt your Googling of lollipop pictures.
Once you finish rambling about the Nigerian Prince, you might take time to surf the CDC's "National Center" (wwwnc.) website for yourself. Oops.
Additionally, the authors' response to the original BMJ article includes this for your consideration:
"We also did an analysis of all mask wearers, and the higher infection rate in cloth mask group persisted. The cloth masks may have been worse in our study because they were not washed well enough – they may become damp and contaminated. The cloth masks used in our study were products manufactured locally, and fabrics can vary in quality. This and other limitations were also discussed."
