  Arguably, it is unfair to exclude racers with disabilities on the ground that crude prosthetics render unable to be competitive, and then also to exclude them when better prosthetics make them highly competitive. Such a practice of limiting eligibility to typically embodied competitors narrows social opportunity for whoever does not conform to the conventional rules of embodiment. And it is precisely because of the ease with which such rules of competition can be rigged to favor some so-called normal modes of functioning over other seemingly anomalous ones that feminists rightly have been suspicious of invoking rules derived from models of competitive recreation as relevant to and regulative of social justice.
