When we are told by scientists that masks don't work, and then, with no new research being done, we are told by scientists that we must all wear masks, it is not science being performed. It is propaganda. I distrust propaganda.
In any field in which I am not an expert it takes time to determine if something that is claimed to be science is really science, or if it is propaganda. I trust the scientific method but I don't trust that people claiming to be scientists are using it.
