Then robbery and assault and battery are also only "regulated", because they have similar conviction rates:
https://www.rainn.org/statistics/criminal-justice-systemAnd I couldn't find data on the average non-federal sexual abuse prison sentence in the US, but for the UK it's 8 years: https://www.theguardian.com/society/2011/may/26/rape-sentenc...
So on what basis, other than "men bad", does the claim that rape is merely "regulated", and that the legal system wasn't (Shouldn't that be "isn't"? Or will we argue about what the legal system was like a century ago, and imply but not state that it hasn't changed?) meant to address it, rest?
In the UK, the police have even withheld evidence from defense lawyers to ensure convictions for rape. Does that affect the claim how the law is basically pro-rape, or is it completely immune to evidence, so long as a single rape can still occur? https://www.telegraph.co.uk/opinion/2018/06/05/basic-tenet-j...
A simple matter of faith, no matter how badly society treats accused rapists: https://www.bbc.com/news/uk-northern-ireland-46235634
