finding a definitively anti-transgender reference doesn't prove your point

Ok. I think I can provide an example and avoid any sensitive topics. Co-ed soccer has different rules (e.g no slide tackles) because women have asked to be protected.

I have never seen an Olympic-class athlete complain about transgender women in sports

That wasn't the claim I was countering. A more general statement was made.

~~Olympic-class~~ women ~~athletes~~ have never asked for protection ~~from transgender women~~ in sports.

The original statement made was too broad.
