Defenders of the three-prong test counter that the genders' differing athletic interest levels are merely a product of past discrimination, and that Title IX should be interpreted to maximize female participation in athletics regardless of any existing disparity in interest. Thus while defenders argue that the three-prong test embodies the maxim that "opportunity drives interest", critics argue that the three-prong test goes beyond Title IX original purpose of preventing discrimination, and instead amounts to an exercise in which athletic opportunities are taken away from male students and given to female students, despite the comparatively lower interest levels of those female students. Author and self-described women's rights advocate John Irving opined in a "New York Times" column that on this topic, women's advocates were being "purely vindictive" in insisting that the current OCR interpretation of Title IX be maintained.
