And you don't know what semantics is.
If you read that link it should be pretty clear that what they describe falls within my characterization of "type of personality disorder".
These people who engage in unusual or unhealthy eating behaviours do not do it because they are physically compelled to do it, they do not have a physical or biological abnormality, they do it as a result of what falls under the description of "personality disorder" as described in the link you provided. The entire issue is in their minds and in their personality. They know that what they are doing is unhealthy, but they derive too much pleasure from doing it, and that pleasure trumps the knowledge of the damage they are doing. Then they feel bad about doing that. The problem comes in when instead of doing something about that state of affairs, or just accepting it as the way they choose to live their lives, instead they point the finger else where. They try to pretend and convince everyone else that their condition is "normal" and "healthy". Part of that process is to point at people who really
are normal and healthy, and suggest that those folk are somehow engaged in an abnormal and unhealthy lifestyles. This is classic "shifting the blame to avoid personal responsibility" that is so engrained in our culture. And underlying all of that is an inherently dysfunctional personality.
And my basic point still stands: we see all this popular outrage and campaigns against "fat shaming", but where is the same response to "thin shaming"? It is not there at all, in fact the very same people who campaign against "fat shaming" for the most part use "thin shaming" as part of their campaign.
There are girls who are naturally large. Over the years I have known a few girl friends who were like that, but they all understood that as a result of their biology they had to eat the proper amount of calories, and could not stuff their face like everyone else or they would just balloon. So, although they were big girls (and in some cases very big), none of them were obese. And there are people, like myself, who are naturally thin. If I ate a healthy diet I would stay thin. The only way for me to get big is to eat unhealthily and/or pop steroids/growth supplements, or become completely obsessed with working out and other such shit. For the vast majority of people, if they ate healthily and were reasonably active they would be neither fat nor thin. But that is not what happens. Most people eat way more than they need to, eat the wrong foods and are relatively inactive. So they end up ballooning. And let me be blunt, just about everyone in modern culture is this way, they consume far too much. Then they feel bad about it, and are caught up in the dilemma between being healthy and enjoying excess. There is no syndrome, disease or any other such excuse, it is all a product of their mind and their personal behaviour, an inability to assume personal responsibility. There is a flip side, namely anorexia, which is the opposite tendency, but that is far less common.
I understand that there are some people who are naturally fat or naturally thin (and since I am one of those people, let me be very clear about that). There is a difference between those people and the much larger part of the population that ends up in one of those two categories as a
result of their behaviour and not their biology. No one should be laughing at the fat or thin, but on the other hand neither should these suggestions that these types of body forms are "normal" and "healthy" be encouraged. The people who are trying to convince everyone else that they are, are flat out wrong and they are doing society a disservice.
