I have to say I'm highly sympathetic. Let athletes take whatever drugs they want, within a clear boundary of non-destructive pharmaceuticals. As long as they aren't damaging their health, why not let them all compete on the same level? Why should random genes have more clout than carefully managed science? Peter Singer goes there. He has a point. The current system can't work; and benefits the genetically lucky and the sneaky and duplicitous. Let's see what science and the human body can give us in sport, with everything on the table. And if non-drugged athletes want their own natural leagues and contests, that's fine too.
