That's an absolutely textbook https://en.wikipedia.org/wiki/Association_fallacy

Is this a false fallacy? If somethong can learn, it can be trained, and that's the dictionary definition of train: "to teach so as to make fit, qualified, or proficient".

The fallacy is "if it can be trained, it is therefore logically a muscle".

Ask your same dictionary to define muscle, and ask yourself if the immune system is a "band or bundle of fibrous tissue in a human or animal body that has the ability to contract".

Care to taste a spoonful of dirt in a sunny day to see how sterile it is?

This is a pretty common thing kids do. They're generally fine.

As a kid that ocassionally ate dirt, you're usually fine after it, if you ignore the worms you'll poop afterwards. My point was that it's not sterile even if it's under the sun all day, as UV rays don't penetrate deep, and dirt is a good thermal insulator. Bacteria and parasites, specially their spores/eggs, can be very hardy. It's amazing what our digestive system is capable of handling.

Except my statement was "If it can be trained, it _behaves like_ a muscle", meaning that muscles and the immune system can be trained.

I don't see how it can be reasonably misinterpreted as "the immune system is literally a muscle", I'm not talking about unfeathered chickens here.

Then why make the point at all as a response to "The air outside is constantly sterilized by UV light"?

Because if sunlight really sterilized the air, which is transparent, it surely would disinfect every surface it touches. In reality, sunlight does disinfect, but life has evolved to withstand it enough to find a safe environment.

BTW, hospital UV sterilizers work better because they're more intense than sunlight's UV.
