But there is a point where being a rational human being is defined by judgement. After all, knowledge and wisdom is the judgemental discernment between the good and the bad.
Smoking, ceteris paribus, generally has bad effects.
Lack of fitness and personal nutritional health, ceteris parbius, is a bad.
Lack of education and pride in ignorance, ceteris paribus, is bad.
In the same way, although we shouldn't throw out or disown members of the human species just because they partake in objectionable or flawed activities (after all, none of us are perfect), it would be a better world if we could recognise that conspicuous consumption, ceteris paribus, is a "bad thing", not something to be admired or desired.
