As a lawyer myself let me offer a thought or two. First, no one here has yet defined in what way he has found women lawyers to be fucked up, yet many have voiced agreement. What are you agreeing on? Is it attitude (and if so, on what issue/s?), or behavior? It could very well be that someone has some quirky thoughts of his own about women that the one or two women lawyers he has dealt with chose to call him on. He then interprets this as meaning that, as a class of people, women lawyers are fucked up (when in fact some self-analysis is in order), yet others just join in with expressions of support.
That said, it is true that women (and men) lawyers are ambitious. Combine that with the fact that law is a demanding and competitive profession and you find that those who do well tend to have little time for bullshit or a whole lot of gentility. What this generally means is that women lawyers, who are analytical and detail oriented by training and practice, will definitely seek to hold their men accountable and will take them to task more readily over all types of things, more often than other women.
Whether this is a good or bad thing is each man's call. C'est la vie. I personally do not like to date women lawyers because the demands for accountability are often too much for me to bear on a day to day basis, and because they can get pretty intense pretty quicky.
