as far as i can tell, homogenised just means that the milk is mixed thoroughly so that it has an even consistency (as normally the fat globules separate from the milk).
 
i don't get what the problem is with this.
 
raw milk from my understanding is unhomogenised, unpasteurised
 
its the heating part that is the biggest concern, especially if you are lactose intolerant, as apparently this kills all the pro-bacteria etc that you need to break down the lactase
