The lack of virus theory is not a theory. Terrain theory is a name the "they" gave it so you other normies could think there are two sides and then you can choose one.

In reality, virologists can't prove that viruses cause disease or that they are contagious. All they can do is take images and do pseudoscience that MSM gobbles up and science institutes owned by cabal push to everyone.

Just focus on questioning germ theory. Don't worry about coming up with some other encompassing theory Like "terrain".

Nothing about germ theory works at all
