I really didn't read her article as unsupportive of Linnehan at all. I've read enough comments here to realise that there is the possibility of reading it as less supportive than I interpreted as. But I certainly can't see it as snippy or unkind.
And things have been so hard for HF too. It must have been exhausting over the years to have been under the pressure she has in relation to gender politics. Plus of course the additional stress of speaking about her Jewishness with anti-semitism always lurking in the commentsphere.
I bet she feels under a knife-edge, writing about Linnehan, and was trying extremely hard to do the subject justice. I'm reminded of Marina Hyde's piece recently, calling herself to account for what she had written in the past in relation to an aspect of the Russell Brand story. She hadn't failed in a very major way, but her own account of not getting things right during 'Sachsgate' seemed plausible and I can imagine how bad she felt. Both her piece and HF's indicate a high-level of self-scrutiny and angst - in a cultural environment where speaking honestly is flat-out perilous, with attacks capable of coming from all sides.
(And why is it two women who have worked so hard to create an honest scrutiny of their own conduct? Oh, yes, I know, because we are the ones who have to be fairer than fair, kinder than kind, etc.)
When I imagine the stress of having your writings so much and so prominently in the public domain on subjects where opinions are harshly expressed by so many people, I'm v v happy to cut HF plenty of slack and put the most generous motives possible on her words.
