If you watch this video of Rebecca W****n http://www.youtube.com/watch?v=O8YSwB8AvWs with the sound turned off you should be able to get some insight into the mindset of hostile feminists. The effect is further enhanced if you pause it randomly to capture the micro expressions.

The various expressions; particularly the eyes and mouth, are quite revealing. The absence of sound eliminates distraction from the body language.

Thanks to the great Oliver Sacks for the idea
