My point is that the allegations are gender-based in nature, which makes this a gender issue by definition.

This did not become a gender issue when "other people support[ed] that claim." This became a gender issue the moment Julie claimed she was harassed because she was a woman. Whether her claims are invalidated or not doesn't change the gender-based nature of her claims--it would simply mean that her claims (which are still gender-based!) are not supported by the evidence.
