Raw milk itself isn’t bad, it’s just very very easy to get contaminated with pathogenic bacteria.
Proponents of raw milk claim it has health benefits due to the lack of cooking, both on a chemical level and a bacterial level.

Raw milk itself is fine, it’s in fact incredibly nutritious- which is why it’s so difficult to keep it from being contaminated. It’s a great breeding ground for pathogens.
In my mind, anti pasteurization types are like anti vaxx light, they didn’t have to live through times where food borne illnesses ran rampant, and therefore don’t appreciate what our scientific ancestors have blessed us with.
