I totally get the OP. I think it IS hard when you imagine that someone can’t bear to be in the body they’re in, that they suffer because of it. I also think that this is a view felt by many women, so I don’t think it’s good to just brush it aside.
For me, the trans debate consists of so many, often contradictory issues. You almost need to know about all of them to see how worrying the entire picture is. So, I spoke to a woman a few weeks back who seemed convinced that being trans was a proper diagnosable, physical condition, that a genuine trans woman would never pose a threat to women, because they were a woman.
So, for me, the big thing is self Id. To be honest, in the past I’d not get too bothered about trans women in women only spaces - because there were so few. Because then it was about gender dysphoria, surgery, and much effort to “transition”. It was always considered a “legal fiction”, no one thought they were literally women. Though I wouldn’t have thought twice about using female pronouns, and respecting the way they wanted to live. But, for me, none of it made sense without viewing it as a person unable to deal with being non conforming to gender stereotypes.
Now, it is almost a lifestyle choice. Children are literally being told that they can have a female body and be a boy, and vice versa. We are giving children a “choice” that they perceive they have to make. Young people are having surgery. Yet older people with male bodies are “transitioning” with no surgery. Sometimes hormones, sometimes keeping a completely “Male” appearance (beard, suit, ties) but saying they are a woman. Stonewall has broadened definitions so that anyone “non gender conforming”, or “cross dressing” is trans. There is less talk of gender dysphoria, of hating your body. More talk of “feeling like a woman”, more reliance on female gender stereotypes.
The net result is the trans categories will grow under self Id. (They already have.) The very notion of being female is undermined. And with that all women only spaces. DV refuges, girl guides, women’s prisons. Predators, be they “genuine trans” or not WILL take advantage because that is what predators do. It will require NO effort on their part to say “I am a woman” when they don’t even have to remotely look like one. A sense of privacy from the male gaze will also go. Even when we are most vulnerable.
Where do the Caitlin Jenners fit into this? I think everyone should make an effort to be kind. I know that in GC circles the view is - no - it’s not up to women to be kind. What I mean is showing compassion without giving up our rights. I have long thought that the outcome of gender self Id will hurt the trans community. I will show respect to someone who is trans, same as anyone. I will acknowledge that they have probably had a hard time of things (though not necessarily the hardest time, nor have the monopoly on hard times that TRAs would have us believe). But I will oppose self Id. Always.
As regards sport, it is NOT a lack of sympathy that is the basis for the argument that a trans woman should not compete against women. It is reality. At the bottom of the problem is that someone wants to change sex and that is just not possible. The OP asks why they shouldn’t be able to compete as a woman. The answer is that because it is not possible to do that fairly. No one has the right to a perfect life, to do everything they want. There are many reasons why people can’t compete in sport. Maybe they’ve had an accident, are chronically il. Not had the opportunities or the time. Maybe they’re just not good enough.
So, I think, yes, have some sympathy for the Caitlin Jenners. If an adult wants to transition, if they feel that to be the only avenue, absolutely fine. They should be able to do so with a diagnosis of gender dysphoria and having shown a clear commitment to that path. But that doesn’t mean you need to support self Id.
