Fairenuff I don't think you can look at a transwoman's body - or any person's body to be honest - and, from a point of no scientific evidence at all, assess that what you see is the basis for significant advantage that will result in a "foregone conclusion".
You just can't.
That's not very scientific, and it shouldn't be the basis on which sports make their decisions. They can't go on the basis of how someone's body looks. That's not very rational.
But look, everyone's fallible, undoubtedly there are instances where their rules have been inappropriate. I don't necessarily mean the pictures you've linked, I just mean at some point, somewhere that will have been the case. By all means let's bring that to the attention of those sports and ask them if their rules perhaps need updating - I'm all for that!
Thanks for the link R0wan, I'm reading it now. And yes, there are issues around sport that aren't just related to the actual competition but also to the use changing rooms etc. I think Swim England for example were right to release "guidance" (not saying it was well-thought-through guidance, but that's another thread...), but certainly each facility needs to take a sensible approach that doesn't disadvantage female users.
