I will say that both paleo and veganism's moves away from dairy are great things, though. I'm a firm believer that a huge portion of our population suffering from IBS, Crohn's, and other random digestive ailments could be in large part "cured" by refraining from dairy.
Hell, I still eat a milkshake or some ice cream on occasion, but I do so with full knowledge that I'm going to pay for it in the coming hours (actually, anyone who has to share space with me is going to pay).
My dad had chronic stomach issues as long as I can remember. He also had a bowl of ice cream for breakfast every morning and a bowl before bed every night. After he retired, he went on a fitness kick and stopped eating ice cream. Amazingly, his stomach issues completely disappeared. I'm kind of astounded that no doctor ever suggested to him that he might experiment with refraining from dairy.
In this world of sin and sorrow there is always something to be thankful for; as for me, I rejoice that I am not a Republican.
