Therefore you should not believe your opinion to be above others; others understand themselves better than you understand them therefore your opinion is merely a second hand opinion of them and less relevant and thus less important. Without the relevant quality of information and indeed understanding of that other individual then you are using one upmanship subjective judgements rather than trying to expand knowledge and to reach relevant conclusions which legitimately assist others and yourself. It's actually self gratification by labelling another as unhealthy you are merely boosting your ego.
In effect the unhealthy label is little more than mental masturbation: "I disagree with your argument, therefore your F/T is unhealthy, herp derp. I vote that this is not a legitimate topic and you are all unhealthy for discussing it!". Le sigh.
