First off, don't misrepresent me. I agreed with you that denying healthcare to smokers and the obese is a nasty idea. But unlike leprosy, emphysema caused by smoking is an entirely self-inflicted condition. No one can claim ignorance about the risks of smoking. Nor can they if they eat an idiotic diet accompanied by a sedentary lifestyle.
Same can be said about red meat, maybe we should persecute red meat eaters the way we do smokers.
