Long time serving Paramedic, and I do have a graduates degree in biology which is how I became a professor of emergency medicine. Glad you took the time to look through my profile like a creep. What is interesting though is you assuming my political views, and then also assuming that has anything to do with the fact that cloth masks don’t do anything OR with the fact that everything I stated above tragically is straight facts without need for polarization. Im independent by the way, so not sure where you thought you were going with ANY of this. At the end of the day, I teach this stuff and have experience with this stuff no matter how much you want to downplay it. You don’t have to be a superduper brain surgeon/far leftist to be an expert on cloth masks.
