Cheating is cheating
We do not live in a black and white world. Some forms of cheating are more severe than others, plain and simple black and white.

To group them all together is to create potential for being misled.
Classifying personality traits as disorders based on the societal "role model" is another example of such thing, for me it is just another social construct.
Sometimes known as: Conformity + Obedience = "The Good". This is especially true when talking about the way young people are viewed.
But if it is true, where is the border between narcissistic personality style and narcissistic personality disorder?
Some would say that it becomes a disorder when it interferes with your life.
Certain parts of Mainstream psychiatry are as flawed as new age studies on paranormality.
Psychology works by creating theoretical models using abstract representations based on indirect observations. This is because psychological processes cannot be observed in a direct and scientific way. They can only be observed indirectly. The theoretical models describe "processes" of the mind, however those models are at the same time used as evidence for the existence of those processes. This is an extremely flawed method. What compounds the problem is that the method is treated as scientific. While the methodology has been designed to give the appearance of the scientific method and the appearance of objectivity, by the very nature of the methodology we know that this portrayal is a falsehood.
So yeah, I'm not big on psychology either.
