These are precisely the sorts of attack that hinder the profession from moving forward (this particular one is especially out there, but I have heard 'academic' sounding versions of the same points). They bog us down in having to defend that sexism is pervasive in the field, so that skepticism about the issue remains alive in even 'well-meaning' philosophy departments. This deters departments from making any substantive changes or taking a stand that may hinder valued ideals of ‘meritocracy’ and ‘fairness’, while touting equal opportunity for all in quasi good faith. While we cannot completely ignore the (often power-yielding crazies), we also CANNOT be distracted from the larger task of creating an environment of meaningful inclusivity.

On that note, I (as I am certain, many others) have appreciated all the work that goes into supporting a community of women through various initiatives, such as, http://beingawomaninphilosophy.wordpress.com/ , http://www.cbwp.ktgphd.com/ , and http://www.womenofphilosophy.com/, and of course FEAST :) 

Best,
