apartheid?

one in four men in south africa admit to rape. that's just the ones who ADMIT it.

apartheid: inhumane acts of a character similar to other crimes against humanity "committed in the context of an institutionalized regime of systematic oppression and domination by one racial group over any other racial group or groups and committed with the intention of maintaining that regime."

Substitute "gender" for "racial" in the above definition, and you've pretty much got it.
sexism is institutionalized.
rape is about domination.
rape is the tool that those with power use to maintain their power.

this isn't exaggeration, it's reality.
