I'd consider myself, as a social libertarian, a bit liberal (for Peoria way to the left) and I believe if you go in this direction it is your right but you should forfeit certain other rights and competing in a physical competition should be unquestionably one. They could create their own league if they feel compelled.
The article mainly focuses on one athlete- born Kelly Godsey- who was born a female, and has been a successful female track and field athlete her entire life (Division III All American 16 times in 4 different events). But in college, she "came out" as transgendered, and declared she wanted to live as a male. She changed her name to Keelin Godsey, and began to live life as a male, and now looks very much like a male. Godsey now lives with "his" female fiance.
However, he chose to continue competing as a female, where he excels and is a strong candidate to make the US Olympic women's team.
The article lists a number of other high profile cases where athletes were transgender and chose to quit competing against their former sex, and switch to competing against their newly assigned sex. In every such case, it involves men who decide to switch to being a woman, and then compete against other women, because it is obviously easier. There are cases involving tennis, golf, soccer, and basketball.
But the Keelin Godsey case poses some serious concerns. As my mother used to say, "You can't have it both ways".
If an athlete decides to switch genders, they should not be allowed to pick and choose which sex they compete against, based not on the sex they are transitioning to, but solely based on what they would be most successful at.
The NCAA will have to decide how to deal with confusing cases like this, especially when the inevitable case arises where an athlete born male decides to switch to female and wants to compete as a female. It is just a matter of time before this happens. The article also briefly mentions a 7'1" former Central Michigan basketball player who played college basketball as a male, but is now transitioning to female. Drew Walker, now known as Lindsey Walker is considering completing the gender switch, then possible trying out for the 2016 Olympics as a woman. At 7'1", she might have a slightly unfair advantage.
