Because, coincidentally, what we'd find is that all of the top level finals were populated exclusively by men.

What you seem to have missed here is that some sports are segregated by things like weight class (not athletic ability, competition itself is what segregates people by athletic ability) and sex. At least at the elite level.

Olympic weight-lifting, for example, segregates by weight class and sex. Yet if you compare male and female records from similar weight classes, males are stronger in every single category of lift.

There is no "cisgender side of the house." This is such a sad, small-minded, counterproductive way to look at the world. Isn't the point that we all see and understand and accept each other? Do we have to close our eyes to obvious realities in order to do that?

What I find so frustrating about this discussion is how the condition for not being a transphobe as far as the online trans activist community is concerned is to accept a level of dishonesty that people who know what they're talking about simply can't tolerate. I'm on trans people's side. I want trans people to live their lives with safety and dignity. I want them to get the care they need. I want them to be treated with the same respect that every human being deserves. Just please stop asking me to pretend not to know things that I know in order to prove it!
