I watched the women's 800M final and think it's unfair that they have to compete with Semenya, who won gold.
Kenya's Margaret Wambui won bronze and I have to say she looks more like a bloke than Semenya. I have no idea if she has had to undergo any specific tests.
I felt for Lynsey Sharp and the other girls, as they do not appear to be competing on a level playing field.
I wonder if there are enough women athletes with extremely high testosterone levels, who could compete in their own event, so that everyone gets to compete on more equal terms.
It's extremely difficult, as whatever action the IAAF take, someone is likely to be disadvantaged.
I have great sympathy for ALL the athletes.

Very difficult issue and no easy solution which, as Michael Johnson said, wouldn't disadvantage someone.
It's been suggested that Semenya is almost trying not to run too fast, imagine the headlines if she broke the (incredibly suspicious) world record last night?
They used weight lifting and fighting (eg boxing & Taekwondo) as an example - in these sports the competitors are divided into weight categories, whereas in most of the other disciplines they are not. This is probably for historic reasons, but different body types are going to have advantages over others, Usain bolt is just so much bigger than most other sprinters, Phelps also has the advantages you mention.
No matter how hard people work they are likely never going to be as good as Phelps/Bolt etc. so is this fair, should things be changed to make things more of a level playing field like in the aforementioned sports? Imagine someone in the mens 105kg+ competing against a 56kg.
Has there ever been a case of someone having a sex change and then trying to compete as their new legal sex? Wouldn't this cause an issue - if Semenya having naturally higher testosterone levels causes such major issues for some, then surely if someone has a sex change that would be even harder for some to accept.
Interesting topic!
It'll be interesting to see how "gene-doping" goes over the next decade or so. The article I read made some good arguments for it, such as it making athletes much healthier in the long run. I'm not sure myself, but interesting times ahead.
Heightest.
Would ya?
I want to play in the nba but all the other guys have an advantage in being 7ft. I wanted to be a swimmer but my size 9 feet couldn't paddle fast enough. I wanted to win the national but I'm not a horse. The only thing I was good at was whaling and that was by stripping off and infiltrating the pod. They've now banned that so tough shit on me.
At what point do we draw the line on what is acceptable? Kids or adults are pushed in to sports based on what they are. Even in isolation football had the same rules. The fat kid plays centre back, the fast kid upfront, the manager's son is captain. Are we going to start moaning about every advantage someone has over their competitors when they are using whatever they were born with.
