Me thinks someone did not do so well in psych 101. Just because you do not understand something does not mean it is a pseudoscience. There is plenty of biomedical (e.g., structural and functional brain studies), behavioral, and genetic research that converge on the same conclusions, conducted by people with big egos who have no interest is propping up other peoples cute little pet theories. In other word, the science of psychological disorders is cut-throat and you better have evidence to support you're claim or else you will be intellectually mowed down and decapitated. This is not a tiny self-contained group of people patting each other on the back and playing a game of "Yes, and...". These are not members of the Lone Gunmen.
