So, to focus on virology for now, it's the claim that viruses have never been shown to exist. So far, every time I've tried talking about it, I've been met with bad faith arguments and derision. I'm a critical thinker and won't waste any time with bad faith stuff (e.g. logical fallacies or insults). I've simply never seen the arguments from us actually addressed properly. Everything I've heard people say has been addressed by the anti-germ theory folks (not sure of what to call them... scientists?). This is a really good essay against virology, I won't respond to any ad hominen (attacking the messenger), I really only care about the actual information revealed in the message and will only respond to that: https://drsambailey.com/a-farewell-to-virology-expert-edition/
