I think a brief (very brief) definition of critical theory might be useful:
Critical theory grew out of a school of german marxists in frankfurt in the 1930's. Initially they were trying to define 'real democracy' ie a utopia and trying to reconcile what they thought should be happening with what was- the rise of facism. The movement initially took a great deal of influence from the philosopher Immanuel Kant. Kant placed extremely high value on philosophy over other disciplines and did amazing work on his theory of the mind. He is also barely understandable to most people and frequently coopted words into his own jargon.
Right from the beginning then the movement was political, valued subjective opinions that fitted with their philosophy and was in the habit of redefining words to fit their agenda-see 'real democracy' mentioned above.
Since the 30s it exploded through western marxism to become this vast hydra we see today with countless splits and subfactions looking at all sorts of issues. There is always an emphasis on philosophical argueing and words are often redefined to fit agendas.
The emphasis on philosophy is why they argue so hard that, for example, gender is a social construct- if they have an issue with a gender role they need gender to be something social so they can criticize it and the society it comes from. This is perhaps easier to illustrate than explain.
Problem/point of interest :women are less common in the millitary than men.
Critical theorist: this is the work of the patriarchy enforcing gender roles. It is to be dealt with by altering our society so equal numbers of men and women are represented.
Realist: this is the result of sexual dimorphism leading to men being stronger than women and historically making better soldiers. With the increasing mechanisation of warfare this is not necessarily still the case. Though there are some roles which still are better performed by men than women due to a reliance on physical strength.
Notice how the critcal theorist uses philosophy - the concept of patriarchy. To justify a political change to fit an ideology- equal numbers of men and women in everything. Empirical reasons for the statuts quo are ignored as the philosophy is given primacy as per Kant
.
There is a certain dishonesty about the way what are essentially philosphical musings are presented as absolute fact that really irks me.
But I think critical theory is useful where it's useful, which becomes a lot clearer when you remember that human zoos that displayed the 'primitives' were first introduced to Westerners under the guise of scientific 'ethnological exhibits' and stuff.
Critical theory came in far too late to stop these though. When i was first being introduced to the social sciences we were given a course on the importance of ethics, objectivity and the scientific method. It was excellent but it wouldn't have been acceptable to mainstream critical theorists as it criticized using unnecessary jargon, avoiding personal bias and declaring them and using purely subjective rhetoric based arguements.
I like your pokemon article, there is a thomas the tank engine one floating about somewhere.
EDIT: Found a copy, its also been in the guardian and several other news and blog sites:
