rape culture doesnt exist in 21st century america.
21st Century America/UK Western Civilization is the epitome of rape culture though.
The reason you don't see women protesting this in countries like Iraq, Iran, 3rd World countries is because they operate on different standards and cultures. Western Civilization is held to a different standard to those living in and outside of it. Women in general in those areas don't have the rights women in the Western world have...
In the Ukraine, women are reduced to sex workers because the lack of opportunities for them are presented by male leaders and frameworkers. These topless protests started their and eventually came over here and became an oddity and a spectator show devoid of true meaning.
But that's because of the fact that America and Americans are too quick to lose sight of the problems in order to create viable solutions based in any sort of reality.
In America, yes....rape culture is defined by sexism, a pornographic/sex driven way of looking at women, double standards presented towards the opposite sex...and most important a PATRIARCHAL (ie led by MEN) society in which men dictate the rule for everyone...even the rights of women.
