"I do wonder if, certainly on GRA, the conservatives at least might not be quite as captured as others. "
Yes that's true. I do think it's often harder to determine how genuine the Tories are on this, as it's an obvious area for them to jump on to gain votes/support. They're not exactly known for their 'women friendly' qualities!
I've spoken to 4 MSPs in person on this, 1 SNP was awful, the other was good, Labour MSP was excellent (but is stepping down at the end of this parliament) and the Tory one was good. Not 100% aligned with my views on it (we clashes on 1 key point - being able to request a female only HCP) but we had a decent conversation.
Even though the Tories are trying to walk back on GRA reform, there's still some v loud Tories pushing this (Penny Mordaunt, Quentin Crisp, Caroline Noakes etc.).
