Yes, I read Conundrum a few times back in the late 70s or early 80s, seeking some insight or validation of my own gender dysphoria.
At the time, in my late teens, I found the book a little underwhelming and to be honest, was also balancing and absorbing critical viewpoints from a number of sources, including Janice Raymond's The Transexual Empire, as well as other trans autobiographies and articles (e.g. Caroline Cossey, Renee Richards etc) and a handful of social science/observational works, as well as picking up snippets of news about Sandy Stone, the Michigan Womyn's Music Festival, but
But this is how it worked back then: you're young, you're not really sure what you're dealing with except grappling with this enormously subjective but ultimately unknowable impulse to actualise, at considerable risk to your personal privacy and safety. You need to keep things secret from your family etc... but there was no internet. You had to rely on libraries, books, magazines, tiny little local support groups, ordering books from overseas etc.
I'm in my mid-50s now, many years since I moved to the UK and underwent full reassignment, a process that wasn't fully supported or understood in other countries that I've lived in when younger... and I must admit – perhaps like Jan Morris – being a little discouraged by the retro nature and entrenched views of some of the discussions I've recently seen across published and social media. I've also fought my own considerable wars and a large part of me is done with reductionist, essentialist or unresolvable circular argumentation and persuasion with unreliable allies wherever they're found.
Coming back to Janice Raymond's critique of Jan Morris's book (or selected passages), I found some of her views highly resonant, but in other places, overstated, polemical and inaccurate... as well as reductionist, but it also challenged my thoughts in ways that have stayed with me for many years.
However – and I don't want to derail this thread too much – I take a slightly sceptical view towards some proposed changes to the GRA, but will also admit that I'm not following the policy and legislative details that closely. Having worked with physically-challenged children and teenagers, as well as elderly people in a professional capacity, I'm sympathetic towards opposing arguments, particularly around the safeguarding of vulnerable people of all ages...
