testosterone soaked children's brains tend to do better on spacial reasoning tests, not that that should preclude anyone from having a job or following any path they desire.

The issue is men trying to compete in women's competitions.

There may be an argument for not having separate tournaments for women at all, but while there is such a division, it's essential to filter out men for this purpose - including those who pretend to be women.

Thank you for explaining it to me. I feel very differently about it (I don’t think there is any pretending involved), but now I at least understand the other side of the argument.
