I don't think the argument proves this much, and if it does it's easily fixable. I agree that in this sadly plausible scenario, "The men, being nerds, handle rejection badly." They are upset, but are they uncomfortable? Not necessarily so, and even if they are I don't think the emotional response is the same as a general feeling of "creepiness". I think the difference is that creepiness includes not just "unsafe or uncomfortable" but "unsafe AND uncomfortable". The physical and emotional response of being rejected is not the same as the physical and emotional response of being hit on in a "creepy" fashion.
