agreed, testosterone (or other hormones) are a flawed system for categorising competitors. so is weight class, as women generally have a higher body fat ratio. so is any system we can come up with. however what I categorize MYSELF as, is probably the worst system. trans people should, like any other person, be able to do sports. but to have competition we need a better system then people choosing their opponents.

so that is why i am asking what systems you guys suggest.
