> If you were breast-fed, you drank raw milk as a child

If people were drinking raw milk directly out of the udder, in a clean environment and blessed with a baby cow's immune system and microbiome, that would be pertinent, but they aren't. Even human breast milk extracted in a clean environment with sanitized tools gets risky very quickly when stored.

I expect the average human mother maintains a higher level of sanitation than the average cow.

At that age you've mostly got your mother's immune system, so it's a little different.
