For all of human history until the last 100 years, people drank milk directly from cows' udders. Who are you going to trust? 10,000 years of human history of 100 years of pasteurized milk? Who got us to this point in history? Your ancestors or a generation of people refusing to have kids? Traditions survive because the people who follow them survive. Drink raw milk and foster another 10,000 years of human flourishing.
