@mcnado The thing that drives me positively wild is that YOU CAN LITERALLY JUST GET A MICROSCOPE AND SEE GERMS YOURSELF!
All these people floating ridiculous "alternate theories" (misusing the word theory to instead mean "baseless claim" rather than theory) that it's all other things could literally just buy freaking microscopes.
Heck, if they think someone is magically beaming fake images into them, they could make their own microscopes. It's ultimately just lenses. It can be done.
