I dunno, I think it's not a bad go at trying to sort out inclusion and representation across the board ('board' pun not intended), and whilst I'm bored of tokenistic "representation" without purpose, actually in a role like this i think ensuring you have a diverse group is necessary and important.
I think I might be one of the "some feminists" mentioned upthread as preferring to describe women as a minority - depends on context of course but if we're talking about being minoritised, a group experiencing systematic discrimination, often a mathematical minority in eg the workforce or most spheres of power and influence, I don't think it's a problematic term. Likewise what we often describe as "ethnic minority" is in fact... a global majority, and also a mathematical majority in eg my son's (London) school, so mathematically it all depends on your definition of the wider population really.
I think people who identify as genders other than their (observed at birth/reassigned in old-style 'transsexual' terms) sex obviously exist, and are also clearly minority genders. Do I support creating a process to record this on official statistics or passports, no, am I happy for them to live their best lives and contribute to the vision for Historic Scotland who simultaneously recognise women as an underrepresented and often ignored group, 100%.
I think opposing all attempts at explicit trans inclusion starts to look more like transphobia than defending women's rights, and I'm speaking as someone who has lost friends for beliefs I would call feminist and they would call transphobic.
