You moved the goalpost. You said "It's my understanding the sickness from milk isn't fatal."

You didn't say "it's usually not fatal", in which case I might agree. You said it's "your understanding that it's not fatal", so I was pointing out that your understanding was wrong.

I realize I'm being annoyingly pedantic on this, but I think it's a claim that needs to be addressed. It's important to know that you can get a disease from product X, whether it be from raw milk or lettuce or undercooked beef or whatever. Pretending that you cannot die from raw milk infections is dishonest.
