Old saying that is true (also your brother is correct she is a he):
If it looks like a duck
Quacks like a duck
Walks like a duck
It must be a duck
A robot duck.
A computer-simulated duck.
An overzealous furry in a duck suit.
None of those things are ducks.
As for Castor, she's not a he, she's a hermaphrodite. Is she looks like a hermaphrodite, talks like a hermaphrodite, runs like a hermaphrodite, she's a hermaphrodite.
Should hermaphrodites compete athletically against women? It's a complicated question because not all hermaphrodites are the same, but T-level seems like a good guide. Oh wait, that's racist.
