“Anglicized” is probably not the best way to think about it. The Latin letter “v” was pronounced “w” through the classical period, but had shifted to β or v (fricative) by the third century, long before English existed. V was pronounced v (voiced labiodental fricative) for many centuries. And though we do tend to give the classical period a lot of prestige, it was just one phase for Latin.
Many, but not all, of the anti -pasteurization people believe that there is an invisible “life force” in the milk that is killed by processing. This is an old idea, but this unfalsifiable and unprovable “life force” thinking undergirds a lot of pseudoscience. People believe in getting energy aligned and unblocked and so on, and believe that drinking milk with mysterious life force is more natural.
