“Yes, chromosomes control our sex and that should control our gender. Lying to ourselves about what gender - sex - we are is dishonest, stupid and counterproductive.”
So, then why do you insist the Y chromosome necessarily produces a male, when it demonstrably does not do so?
Because it does, for about 1999 out of 2000 people. And for the 1/2000 otherwise, I’ll give a pass...but they may still be restricted in sports, depending on the exact situation.
