If the authorities involved had a problem with it, it should have surfaced before she was allowed to compete. Wanting to take her awards away now just smacks of sour grapes.
Maybe, but in any case I think it's more interesting to consider the issue in an abstract sense, and I don't think ignoring biology in favour of self-identification provides a satisfactory answer. If we consider the "like against like" principle that prevents dolphins from competing against swimmers, motorcyclists from competing against runners, adults from competing against children, and men from competing against women to be of value in competition, then inter-sexed folks clearly pose a problem. Any system seeking to accommodate them outside the traditional male/female dichotomy faces the practical issue that there simply aren't many such folks around, and I suspect that an "other" category, however labelled and delineated, would be both ethically and practically problematic. Yet if women possessing various male characteristics that serve to confer a material advantage are permitted to race alongside woman without such characteristics, is that not unfair to those women? In the long run, with our increasing ability to manipulate genetic structures, isn't there a risk of creating a women's sporting culture composed (at the elite level) almost entirely of such individuals?
