In 2010, Jenna competed in the Miss International Queen pageant for transsexual and transgender women in Thailand. The result was encouraging, although she didn't win, so she made the next logical step: she applied to compete in the Miss Universe competition in 2012. Only after registering and becoming one of the top 65 applicants, she was disqualified for being born male.
She fought, and won, and was allowed to compete, in a landmark decision that paved the way for greater recognition of LGBT rights across the world. The most fascinating part of the story is that she was essentially fighting Donald Trump, the owner of the Miss Universe competition, a man with a very shaky history with regards to LGBT rights. This was one woman who finally got him to back down, and we're all better off because of it.
