the argument from what i understand is that since rape is somewhat difficult to prove (idk if this is true or not, am not versed in civil stuffs) that if false accusations of rape were heavily punished that people who have actually been raped would be more reluctant to come forward due to that since rape is hard to prove that if found innocent the potential raper could claim false accusation, etc etc.

not that i agree with that, it's just the arguement from what i understand
