I am familiar enough with various feminist theories to teach them at HE level, which is probably more than most posters can claim.
Well, aren't you the superior one? Yet it's interesting that you mention none of these theories, nor how they substantiate your sweeping assertions that are based on absolutely zero evidence, not least quoting evidence that isn't actually there (a no-no that sees essays marked down even at first-year undergraduate level. But then you'd already know that, wouldn't you?).
It's interesting that the TRAs and 'intersectional' drum-beaters constantly quote Judith Butler (in whose later work she herself discredits some of her earlier ideas), or Kimberle Crenshaw, whose ideas about intersectionality have been widely misappropriated and bear no resemblance to the actual essay she wrote. Or never mention the point that 'third wave' feminism never actually took off in the way of the first and second wave (what's it got?: maybe a small handful of 'readers', maximum?) - primarily because it's more akin to washed-out liberalism, doesn't necessarily speak for feminism and couldn't actually define what it thought it was?
It's easy to teach 'theory' in a confirmation bias of one's own personal prejudice, but any bona fide academic knows fine well that there is always at least one - and usually myriad - counterpoints, and that it's essential your students do justice to all sides of an argument. Granted, many of them are so ideologically dripfed with the TRA/Allies' agenda that it can prove difficult or controversial to do that. But it's essential if you want these people to provide themselves with a rounded education and proper critical skills, rather than parroting someone else's indoctrination. But being an HE level instructor, you'd know that too.
Your notion of expertise is certainly not more than the FWR boards can claim. It's populated by biological scientists, doctors, researchers, and academics in both the sciences and humanities. These are women who can assuredly speak for more than this, who can construct arguments and debate robustly, and can base their assertions on something a bit more than hot air.
