What science exactly? That word seems to be used more and more as an all encompassing, unquestionable statement that needs no verification. Even the CDC website doesn’t have any conclusive scientific data that mask actually do prevent covid, it only says “it may.” So what science are you substantiating that stance with? Or are you just going by what the talking heads are telling you? Show me a study that proves the efficacy of masks and we can go from there, I don’t mind changing my position based on facts. Show it to me first but don’t just say science. There’s a lot of junk science out there.
