Granting, for the sake of argument, the basic premise that the latter statement would have greater weight if the proportion of women who would be raped in their lifetime was greater than the proportion of men for whom that is true [1], and granting the assertion about the lower bound on the prevalence of rape victimization for women [2], you would need to also provide [3] an upper bound on the prevalence of rape victimization for men that was lower than that lower bound for women for this to work.
[1] Which I would not grant except for the sake of argument, without additional argument for it, because there are a number of problems I see with that premise on its face, but they are secondary to the more glaring problem of the missing comparison.
[2] Which really should be supported by something.
[3] And, as in [2], support.
