Could you highlight when and where I've challenged the statement that "trans women are women"?
When you labelled Sommers' statement as incorrect (in our apparently shared view). The one you said I was only agreeing with because of some (unspecified) "cultural affect".
Did I read you wrong? Are trans women women in your view? If so, what is your problem with them competing in women's sports, specifically? Could you state it plainly and simply, instead of resorting to vague assertions about cultural affects? Ideally it'd also account for the various existing examples of cis athletes who have had either natural or chemical advantages and have faced no censure. And that's not even touching on financial advantages that will account for any athletes development and performance.
All that said, that's still a rather neat bit of cherrypicking (and the third time you've ignored the puberty blockers bit).
Oh, and FWIW the mother of one of the women at the heart of the whole JK Rowling thing (RIP both of them) was a family friend, and I fought your corner in a number of arguments. I lived in Brighton and my local pub was a trans pub - and most of civfanatics know how seriously I take my local pub. If you alienate a person who is on the 98th percentile to your side you alienate effectively everyone.
Being an ally isn't like having a credit card. You don't earn points.
I'm not doubting what you've done outside of CFC, but what you're doing here is tone policing a known trans poster and assigning some pretty weighty rhetoric to her. And then you got upset when you were criticised in kind.
You're right. The argument you were having was unproductive. But it'll likely continue to be until you recognise your part in it.
The conditional allyship thing is a bit rough as well. Try and work out why the marginalised poster that others have been winding up throughout might be in an uncharitable mood, instead of dangling your support above them until they meet some kind of behavioural criteria.
For example:
Can be, often isn't. And even if you mean it neutrally, it still has heavily-gendered etymology. I'd respect the preferences of the person you're talking to, personally. Instead of characterising them as looking for a fight.
