I listened to a really interesting podcast about JKR a while back. I think it was called "the witch trials of JK Rowling".
What I got out of it was how little nuance and grey there is in all this on all "sides" and I include JKR in that.
I think it's ok for there to be nuance and some things you're ok with and others your not.
It bothers me not in the slightest for example if someone who is trans and presents as female to use a female toilet. For starters, just think of the bloody practicality of it all? If you look like a woman but happen to have male genitalia, who will know? Nobody that's who. It would be far more "weird" for someone who looks like a woman using a men's loo and also probably far more of a safety issue than the other way round. The hoo ha about it all I find kind of ridiculous. You don't think trans women have been using female toilets for years?
But when it comes to sport, yeah I do get the concerns. You have so many physical advantages being a man or many of us would not have been victimised by a man or men in our lives. Men tend to be taller, have lower body fat, more muscle, different bone structure and no periods or hormone roller coasters. Not all of that is lost even if you then take drugs to make your hormone levels closer to women. It was bonkers that was ever accepted.
Kids? Yeah I have concerns about what was going on with giving drugs to prepubescent kids. I think that's fair but it's also complicated, and not something I have direct experience with so it's fair for me to let others talk who do.
I could not give a crap if diversity targets to include women also include trans women. You can bet they're more discriminated against than most and what matters, e.g. on boards for example, to me is how many visible women there are. It matters not a jot to me if those women were born as such or not.
Changing rooms? Shared changing rooms just need to go anyway. I know it's sidestepping the issue but wtf have shared rooms nowadays for safety and privacy reasons. That is the obvious solution or if not needed, remove them. Ask people to change at home. (Even in covid, medical staff were doing this which in some ways is just so bad for hygiene but that's another thread.)
The one place I get pretty black and white about it all though is prisons and refuges. Look, any trans woman who has had an op to change their genatalia to match womens, I have no problem with being in a female prison or refuge and this is not actually a thing against trans either because this is more protection against the idiots who try to pretend to be trans. And let's face it, it's happened. I do understand trans people who choose not to go through operations which could leave them unable to feel pleasure in the future in that way, but there is a wider safety issue here and, to my mind, a square that cannot be circled. By allowing the rights of a minority, you put at risk the rights of a larger group. And sadly the case of Isla Bryson cannot now be ignored.
But the last issue makes me feel really sad. Because I'm also not blind to the fact that there is a protection issue too for trans women who are often subject to as much if not more violence as women. The sh*y thing is it's often cis men who make this all a problem for both cis and trans women.
