Liana & Rob's comment included comments surrounding accommodation for the blind and the deaf.  I don't think that is what Ms. Wente was discussing.  

Show me where in her article she said those disorders were "illegitimate"?  

The question is how much accommodation is reasonable for those kinds of issues, and how much these disorders are creeping into just normal stresses of higher education.  If I am stressed out for an exam, do I have an anxiety disorder and need accommodation?  For example, the list that was outlined by the Human Rights Commission in the article goes way too far in my opinion.
