I fixed the trans athlete "problem" a long time ago but nobody wants to hear it. Just get rid of sports where biology plays a major role. Swimming? Gone. Running? Buhbye. Football? Seeya. At a professional level all these athletes are doing the exact same level of training. The only real difference is their genetics. You're cheering for DNA structure.
Either that or get rid of all restrictions on drugs and body modifications. If someone wants to have hydraulic arms to help their shotput, go nuts. What gender is that roided slab of muscle? You can't even see their head past their delts, so who cares. Was that quarterback born with a penis? They have tank tracks for legs now.
