"He and his compatriots can feel free to write as many manifestos explaining male deficiencies, of which my feeling, female self – with aggressive male undertones – is convinced there are many. "

Well there you have it. Heinen is saying that men have deficiencies that are an intrinsic part of maleness - which can only be biological. 
Can you imagine the furor if a famous male lawyer said something like that?
But let one male at one company write one memo criticising affirmative action programs and the sky is falling!!! This is why most women refuse to identify as feminist while at the same time identifying as believing in equality - we know the difference.
