It was mentioned in Persepolis (2007) that people who were against the revolution were executed by the state.
It also mentions that women from this group were executed in a different manner.
Virgin ones were first forced to marry the revolution fighters, forced to consumate the marriage (rape) and then their execution would be performed in front of public.
Is this true, as in, is this a historical fact? Can anyone prove this happened in real life? Or this was just an exaggeration in movie-verse?
