1.) What the authorities could do to handle Fallon Fox is have a back round check on her.  This way they can know if its safe to fight her opponent.
2.) Transgender athletes do have a distinctive advantage over other athletes.  Males are much larger and have a heavier frame then females which gives them superior advantage.
3.) I would not compete against a transgender athlete.  Its not fair competition and I would rather live.
4.)Transgenders should have their own league. Not because of the way that they are but for safety reasons.
