I really did try to stay out of this thread...
The way those "men" behaved is vile and deplorable. Had I been the woman in that situation, I don't think a little kick of my leg would have been enough. I may well have left in a body bag as a result, but I would have taken at least one of those fuckers down with me.
With that said, I would never have been the woman in that situation. Had I walked in and seen maybe a handful of guys, some drinking, others not, then maybe I'd have gone through with it. But to walk into a room with that many drunken frat guys already horned up by beer and the promise of a live sex show, throw in the obvious competitive nature in such a situation, you walk away.
I'm not victim blaming, there is NEVER an excuse to behave the way those individuals did, but it was stupid and irresponsible for those performing not to walk away the second they saw what they'd let themselves in for.
