I have a feeling that Libby Purves has very tentatively raised the top of her head a centimetre above the parapet before - she's in my mental file of 'cautiously onside' but I can't for the life of me remember why, which isn't much use. I have a feeling it was to do with families/children/mental health (she lost her son to suicide) so could have been around the time of the increased Mermaids scrutiny?
It's truly a cause for celebration that the atmosphere has changed enough that moderate voices feel able to speak up now, thanks to the ovaries-of-steel courage of women like Janice Turner, Allison Bailey, Susanne Moore, Kathleen Stock, Jane Clare Jones, Maya Forstater, Sarah Phillimore, Sonia Sodha, and - of course - JKR, who risked everything and went through hell by speaking first.
