Wow. The wonders of photoshop. 
"Most cisgender women would be completely fine with a trans woman using the showers after a workout, but do I want to risk ticking off some random transphobe? No. Do I want to risk having someone take photos of me without my consent? No."
Funnily enough that maybe true. Women who are happy to be labelled "cis" just may be happy to share showers, although it is possible they are unaware what it is they are agreeing to and they may get an unexpected shock and fast track up the peak.
Personally I certainly wouldn't risk confronting Clymer. There's a history there. Plus a 6 foot ex military body.
No, I'd turn on my heel and run.
