@TheShadowyFeminist - I think the issue of trans is quite interesting in how in has manifested in Scotland compared to England. One of the arguments for independence is the difference in mentality between Scotland and England that this is somehow very fundamental.
What is trans? 30 years ago it was gender disphoria and a very few people had medical treatment. But now it actually arguably covers such a large class of people who can claim "trans" from transsexuals, questioning teenagers, middle aged men with fetishes, it can be a way of life.
All these different tribes as part of trans in public life are not the same. A few are doing something intellectually radical, to say that a man presenting as a woman has identified into being a woman, with the same agonies, requirements for protection, health care, etc. That is from a point of view of public policy, ridiculous because actually it is the biological nature of women that drives the need for single sex protection. Trans can not achieve this, but some ask for that total protection which imo cannot be justified. A different approach would be to look at the evidence of actual need, and then consider what needs to be done for trans people, but that does not entail altering the sex based rights of women (which seems to be the English position and is not going to change).
Its interesting how this has captured public policy in Scotland and associated with the SNP. I think it is part of the emotionalism that has spread in Scotland and transformed its political presentation, which is that nationalism and trans are both about feeling, the perception of being a minority, and the perception of oppression. They sit well together as an intense form of politics, based on feelings, but as with the HCB (which is a terrifying piece of legislation) law cannot be made on the basis of feelings, it must look at need, harm, actual requirements to be effective if it is not just to tyrannise people into "good behaviour" in some arbitrary way.
