One thing that people should be upset about is not whose math is right, but one side of discussion was removed from youTube. I thought this is freedom of speech country. When some YouTube employee setting now at home can remove anything from YouTube because he or she do not like it we all should be upset. This sounds like what is going on in China. YouTube actually said on CNN that they would remove a video that said vitamin C will stop the coronavirus. How do they know if does not work. People need to use common sense. We keep trying to protect stupid people.
