It does have such a basis--maximizing opportunity.
It does not maximize opportunity. It funges opportunity from one group to another. Repeated requests for an ethical justification for this funging have been met with silence, or hand-waving, or (in this case) empty equivocation.
It needn't be harmful to women,
Men transcending sex segregation in sports is necessarily harmful to women. The harm is unavoidable.
and I'm at a loss as to how it's harmful to people with "actual" gender dysphoria.
Any time someone adopts the identity of a medical condition they don't have, and demands accommodations based on that identity, at the expense of others, it's harmful to people who actually do suffer from that condition, and are looking to their society for a sane and humanitarian response to their actual needs.
If you're calling someone a scumbag for attending to her own well-being rather than maximizing her performance, I don't know what else to call it.
You're begging the question that this is necessary for Thomas's well-being.
My entire line of inquiry about medical diagnosis and prescribed treatment is about whether there is any good reason to believe that any of this is necessary to Thomas's well-being, let alone so necessary that it trumps the well-being that is to be lost by those disadvantged by her choices.
Women are losing out in order to accommodate Thomas. What's the justification for that? We know it's not medical.
I don't have any interest in relitigating this for people with short attention spans.
Are you talking about
this post?
It is a strawman. Nobody has said anything remotely like "women's well-being doesn't matter", and that isn't necessarily the consequence of trans-inclusive policies.
That women's well-being matters substantially less than trans-inclusion is a necessary result of the trans-inclusionist policies being proposed and enacted. Not only is it obvious just from examination of the policies in theory, but we actually observe it in practice wherever these policies are put into action.
Women are significantly more likely than men to support trans rights across the board, including on the issue of inclusion in sports. I find that difficult to square with the idea that this problem results from disregarding women's interests, at least not without adopting the attitude that the poor dears should be protected from themselves.
Appeal to popularity. There are women in this thread who do not support the trans rights under discussion here. They have made rational arguments for why they do not support this. Can you address those arguments?
