It isn't, you are just being dishonest.

It's not my fault, the Holy Misandry Council have my father hostage. All hail the Supreme Yoni. Just kidding, here watch this. If I'm lying, so is Jackson Katz. (inb4 sarcastic dismissal of a ted talk; he's a respected academic, unless you automatically don't respect feminist or queer theory. If that's the case, we probably won't see each other's points)

(For men it doesn't say "from their most recent or current partner", but if you read the methodology, the entire study (for both men and women) is only about the most recent partner)

Can you not see how this proviso limits the scope of the research in terms of its applicability to the general population. People get raped outside of relationships. People have been raped by other people who are not their partners. Another limitation involves rates of reporting:

Sexual assault has one of the highest violent crimes committed in Canada. However close to 9 out of 10 women hurt by sexual assault choose not to report.

This study (in the way you have deployed it rhetorically) is like trying to determine the monthly rate of shoplifting from a grocery store by counting up how many grapes have been sampled by shoppers in the past five minutes. Try harder, harder. Or just go read and stop arguing on the internet. Either/or.

Speaking in the report's favor, we now understand (thanks to feminist organizing and activism) that its possible for people to be raped in a long term relationship. Prior to 1983 in Canada the (limited) subject of this study wouldn't have been taken seriously.

I, a feminst, understand that Men get raped. Straight men, gay men, trans men and boys are raped, sexually assaulted and coerced (usually but not always by other men). Does it warrant study and action? Absolutely. Is it a knockout argument for why the videos above are sexist? Not by a long shot. They are heteronormative and limited in scope, but that's another discussion isn't it?
