There are so many different ways to analyze rape culture so my hat's off to Fawn! :)

Anti-rape clothing?  Is it a prevention? Yes.  Does it work? Probably not. But is it more harmful than a woman making sure her keys are in her hand if she's walking in to a dark parking garage?  Stranger rape is not the majority of rape cases but I also agree that they are what instills a fear, conscious or not, in women. One of the links in the article went to blog called "Stop Street Harassment" with the quote "A world without rapists would be a world in which women moved freely without fear of men. That some men rape provides a sufficient threat to keep all women in a constant state of intimidation, forever conscious of the knowledge that the biological tool must be held in awe, for it may turn to weapon with sudden swiftness born of harmful intent.” – Susan  Brownmiller in Against Our Will: Men, Women, and Rape (http://www.stopstreetharassment.org/2009/11/an-underlying-fear-of-rape/)  I think she is right on target - it is that turning into a weapon part that implants fear in women.

Do I take precautions? Yes. Would I buy special AR clothing? No. There is a fine line between protection and paranoia.
