We have an extremely small subset of humans who feel non-typical enough about their gender at birth to change it, and go through all that entails (definitely not a "whim" event). Once they've done it, they just want some acceptance, but instead their lives are threatened regularly, and they're blocked from participating in many aspects of life, and one aspect they particularly enjoy. My morals won't let me come down on the side that wants to persecute these humans for the temerity of wanting to sport. I'm not a sports fan any more, but, to me, this fuss about transgenders really makes sports fans seem weak and fearful and hateful. It just reinforces the big bully jock stereotype for me.
Systemic problems often seem to get solved by overcorrection and radical action. We've been off course for quite a while, so just steering a bit left isn't going to work. We may need to go hard a-port for a ways to get where we want to go. That's if y'all want to go to the same place, where our equal rights are guaranteed and actually in writing, and humans are respected more for themselves than how well they fit our expectations.
