None other than the NYTimes’s Mark Bittman sounds like a vegan polemicist:
Most humans never tasted fresh milk from any source other than their mother for almost all of human history, and fresh cow’s milk could not be routinely available to urbanites without industrial production. The federal government not only supports the milk industry by spending more money on dairy than any other item in the school lunch program, but by contributing free propaganda as well as subsidies amounting to well over $4 billion in the last 10 years.
These aren’t new arguments, but Bittman presents them well, citing his own experiences. And of course it makes a difference that he’s a charming, high profile Times columnist.
