After all the information you supplied indicating that this transsexual female has an unfair advantage, you just obliquely quip your own personal bias. You should read your own article.

We have long had strong rules and laws against competing in sports with the assistance of drugs and other medical tricks. The Soviet Union, and now Russia, have been notorious for doing everything they can to circumvent these restrictions. The pressure to be an Olympic champion, and the rewards if successful, are immense. Do not be shocked to see second tier Russian men competing as trans women in multiple sports in the future. A few years of hormone therapy and acting feminine are a small price to pay for a gold medal that will secure your future.
