Caster also has significant personal gain here to keep being able to compete against women because they would be uncompetitive at this level against men. There goes the fame, money, sponsorships.
The machine around Lance Armstrong was also very, very big, and I also think he has personal responsibility for the manipulation and lies he told the public.
There is a huge business around people who are at the top in sports, but these are adults who are fully aware of what's going on and they could stop the machine if they wanted to. It's not like the young people in Eastern Europe and the USSR who were given 'vitamins' and didn't realise they were steroids.
It would be very difficult for Semenya to change stance now, though, after spending so long insisting on being allowed to compete against women.
If people can escape personal responsibility, this will keep happening because everyone focuses on how sorry they feel for the “victim”
It's funny how they don't see the female competitors as victims of unfair competition, though.
