The author is clearly extremely intelligent and accomplished, and you'd have to walk in her shoes to know her true experiences.  On the other hand, as someone who is embedded in the Bay St firm culture, I have to say I do not fully accept that women of colour are not well accepted.  Succeeding in that environment is like climbed a greased pole.  Everyone finds it challenging and attrition rates are high.  My experience suggests you actually CAN be yourself, and if you're a good lawyer, provide great legal advice and generate client work you can succeed.  The towers at King and Bay aren't made of ivory and aren't full of entitled blue bloods.  Law professionals are typically trying to do good work and make a living and, respectfully, I don't know of anyone who spends a lot of time thinking about who "belongs".  Also, I find the timing of the article opportunistic, being a couple of days before the major recruitment cycle for law students kicks in.
