Titchy, you are also being too simplistic on those stats.
Let's make the reasonable assumption that to be raped by anyone other than a live in partner, a woman has left her house. If she is raped by a date, a non live in boyfriend, a friend, a stranger she met that night or an acquaintance (ie anything other than a chance encounter in the street/park that led to, effectively, an abduction to a place where the assault could happen) - then she was probably socialising at the time.
In order to properly test your proposed correlation, you would need to know what proportion of women on a date in a bar were raped vs what proportion weren't. How did these proportions vary with the number of units consumed? Were the women sticking to soft drinks safer than those having two glasses of wine? Was there a stronger or weaker correlation between incidence of rape and the amount the man had drunk? What about other factors - was rape more likely on the first date or the fifth? What about if the bar was in a town centre or at a country golf course?
What about attempted rapes? Was there any correlation between "fighting off" the attacker and any of the above factors?
And, the great untestable - what was in the mind of the men with these women? Did they ever have any intention to rape which was thwarted by canny drink management?
And please stop likening it to the freedom programme. If you are saying what the victim wears/drinks/says etc makes her more or less vulnerable to rape, you are assuming that there's an element of very short term choice to the rapist's victim selection. The freedom programme is about making better long term choices.
