The standards that they use to define alcoholics would have included Churchill. I am sure that this would give the authors of such standards no cause for second thought. The fact that a great man from the past would be classified as suffering from a disease would only make them more confident in their own superiority.
What is so unpleasant about our age is that it crows about its tolerance while being the least tolerant of other societies, times and cultures that differ from our standards. It is not that our standards are different, it is that we are uniquely inclined to define deviations from our standards as pathological.
