When it comes to underreporting, estimations are that male underreporting rates are 80-95%, female rates are 50-75%.
Okay so male under reporting is higher even on the low end to almost no reporting at all. But you can't see how the numbers are skewed?
If more women report something then men do, it'll look like women are the ones suffering more then men.
The reality is GBV effects both, but as usual men don't get any help or sympathy, hence the higher suicide rates, alcholism, drug addiction and other crippling issues.
Society has dictated women cannot be wrong, cannot be abusive, cannot murder and and.
Hell women even think that if they ruled the world would be a better place as they wouldn't declare war as much. But history indicates they are 27% more likely to do so, even 20th century proves that.
Just taking your numbers as an example, out of a 100 women 25 to 50 report it, out of 100 men 5 to 20 report it. See the massive difference in under reporting? Plus how it's skewed in the "official" reports.
