@Kinnison The Amish farm over yonder sells raw milk. I haven't ever drunk it because my guts would probably explode.
But besides that ... I think stories like that bring it to people's attention. "There's raw milk? I wonder what that tastes like." Then they go looking for it.
The Amish also have unhomogenized milk. I've had that. It's good. You have to remember to shake it.

Even Pregnant Amish women do not drink Raw Milk. They know how bad it can be for a developing fetus
