Thanks for adding your experience to the debate.
All I’m suggesting is simply for anyone involved in sport to be matched up with people of similar capabilities. So, if I want to go and play tennis, I can be matched up in my local Division 12 (or whatever division would suit my ability) and I will be playing against both men and women, including perhaps transgender men and women. That way, no-one even has to be asked what their gender is, in order that they can compete in sport. Would you have an objection to that solution? And if so, what would that objection be?
