Thanks for the link. I thought I saw something similar years ago. I'd imagine that the those who don't react to the gal beating him in public continue to carry the idea that men are strong enough to handle whatever is thrown at them. a fun experiment would be to use a female body builder and a similar built guy from the video and see how many people jump to her aid. Then switch roles. This may affirm or disprove if the situation is based upon a percieved weakness or remains with gender.
