Trans athletes make great gains, yet resentment still flares

I don't think so. It's not about the sports in my opinion. It's about our understanding of the human person. The sports issue serves as a visible manifestation of a larger idea which is why it's something of a flash point.
But I am trying to KISS. I know I wouldn't be talking about this issue at all in this thread if it wasn't for sport. I am not trying to complicate it by talking about how a trans person lives outside of the world of sports. Some people keep trying to bring it in just to keep making it more and more complicated and, again, I'm not getting on that merry go round.
