Man Named 'Tiffany' Is Dominating Women's Pro Volleyball in Brazil

They're female because that's how their brain is wired and because I respect the fact that they identify as such.

If that's your opinion then wouldn't you think that the regulations monitoring hormone levels to ensure fair competition among women would be discriminating against transgender females? Otherwise, wouldn't you be saying they're still men?

No, they're women as far as their gender/sex is concerned. The problem is that with transgendered and transsexual women, their bodies are too strong for cisgendered women. So when it comes to women's sports, we can't overlook such a distinction. In the case of F-to-M, this isn't much of an issue as men aren't disadvantaged by transmen who compete with them.
