So I believe that we all have the right to identify however we choose regardless of our gender at birth.
But
I also think that women have the right to be safe and due to the risk to women that men pose I feel women do need safe spaces and also their own space in sports otherwise they risk losing their identity in sport. So to me the answer is womens spaces, gender neutral spaces and mens spaces. Gender neutral encompasses male, female, trans male, trans female, gender neutral, pan gender, non binary etc.
The way I see it is we live in an inclusive society that recognises peoples right to live their life as they choose but the need for women safety is paramount.
