Joe Rogan has a few podcasts where he debates the issue of transgender M to F athletes. I agree trans should be able to compete if a sponsor is willing to create a trans class otherwise they are welcome to compete in men's classes. The trans athlete will have significantly stronger bones, more mature muscle mass, stronger tendons, faster reaction times, and in a lot of sports the male pelvis/hips are an advantage. It's not transphobic, it's common sense.
