@PalacinkyPDX I doubt she “swallowed the red pil or orange koolaid”. I was thinking a serious disagreement between her and a trans-person or a TERF brainwashed her.

Is it common sense? The is a runner, Caster Semenya, who is being prevented from competing because her body produces more testosterone than most women. There are also people out there born with better reflexes, or above average strength. It's called biodiversity. We all have different bodies. I am pretty sure short runners are at a disadvantage to tall runner as well. Have you ever heard of classes of runners based on height? Much more likely that a very short runner doesn't compete because they can't win against long legged runners. It is not like some man who was a great runner suddenly decided to transition to a more female body just because he thought it would give him an advantage. Just doesn't happen.

I think you want to use the diversity within a gender group as a reason to extend the diversity to allow a woman with masculine abilities to compete with ordinary women. That's not fair. You might as well bring it to its logical conclusion and get rid of the gender barrier in sports altogether. That would be an interesting experiment.
