My main concern about the source article was that, after a series of nuanced pages, it devolved into a reductive, binary representation of GC feminism in polarising language. I don't think strong language or one-word qualifiers - "ultra"/"lite" - are particularly well-suited to such a complex situation.
Like it or not, Sapir and Whorf had a point: language does help to construct reality.
We're challenging the post-modern deconstruction of the man-woman/male-female binary precisely because, when language has such power, its conflict with material reality has a dangerously destabilising effect in societies in which accommodating biological difference is key to women's safety, health and well-being.
Where a perceived opposition is, in contrast, conceptual not material - impossible to pin down, and almost certainly on some kind of opaque spectrum - I think binary terms, conversely, serve to solidify courteous disagreement into apparently concrete, but wholly artificial, divisions.
Let's debate, respectfully disagree etc., but all within the overarching understanding that GC encompasses a range of different views unified by the conviction that women are a class in their own right, with their own rights.
I do think that one of the key weak points in this ideology is its impractical, dogmatic compulsion to put the abstracts of human nature into own single, neatly mis-labelled boxes. There's a fab quote from Shakespeare (and no doubt loads of others, too) about an object that's flexible having greater strength and longevity, while one that's unable to bend is more brittle. Let's be the reed in the wind, just inclining different ways. Or something. Wax on, wax off. Ahem.

(It's driving me crazy that I can't place the Shakespeare one...)
