Milk is a pale liquid produced by the mammary glands of mammals for nurturing their offspring before said offspring are able to digest other types of food. The word “milk” comes from the Old English “meoluc” (West Saxon), the Proto-Germanic “meluks,” and the Old Norse “mjolk.” In the Middle Ages, milk was called the "virtuous white liquor" because alcoholic beverages were safer to consume than water.
Lactase is an enzyme which is necessary to digest milk. Although lactase normally ceases to function once a child matures, a mutation occurred in European populations roughly 7,500 years ago which results in lactase remaining active even into adulthood. Thus, most European adults—an estimated 80% of all Europeans and nearly 100% of Northern Europeans--are genetically able to digest milk. Interestingly enough, 75% of Jews are lactose intolerant. Thus, white milk is racist and counter-Semitic and it is yet one more manifestation of evil White privilege.
If a person is lactose intolerant and disregards the social construct that is lactase persistence by consuming milk, they can require hospitalization.
Scientists theorize that Northern Europeans enjoyed the selective positive pressure of “lactase persistence” because the growing season is shorter there in the colder climate, and the colder climate resulted in natural refrigeration insofar as milk remains milk throughout the day in colder temperatures, but can become yogurt if it is stored in warmer temperatures. (Yogurt, like cheese, is easier to digest than raw milk because it contains less lactose.) During times of famine, people who were able to consume raw milk survived; those who could not starved. Thus, the genetic mutation spread like wildfire.
The benefits of lactase persistence are profound: milk consumption permitted Europeans to raise livestock for milk production, which provided a reusable nutritional source which did not require animals to be put to death for their meat. Thus, food production in Europe was superior and more efficient than other places on Earth for thousands of years, and this contributed to nation-building in Europe. While other peoples were able to subsist as nomadic hunter-gatherers, early Europeans were able to farm and establish territory and concepts of land ownership—which required government to protect the same from foreign invaders.
Although some movements have embraced beer (i.e., Bier Hall Putsch), vodka (i.e., Stalin’s communists), and wine (i.e., Alexander the Great’s conquering armies), the drink of choice for the American Alt-Right activist is white milk. This recent development is best shown via National Policy Institute’s Richard Spencer flaunting his lactose tolerance on Twitter in his biography and with a white milk emoji, and Alt-Right shitlords showing up to Shia Labeouf’s art exhibit to theatrically consume white milk. Leftists are now yelping online that “Milk is the new, creamy symbol of white racial purity in Donald Trump’s America.”
