Although more than willing to accept some men just dont get it, but anyone who has any contact with what is known as the VAWG sector will know that for a number of years even those working for rape crisis or women's aid regularly talk about gender based violence.
I am not even sure many of them are that aware that it is a total corruption of their purpose to support women who have suffered violence because of their sex.
Gender based violence sounds like someone getting up set that someone doesn't dress or behave in a gender conforming was.
Even the International Day for the Elimination of Violence Against Women (you can read the original founding principles) is now "celebrated" by not only institutions but women's groups and campaigns as being against "gender based" violence.
A lot of this dilution of reporting about women specific violence or health or whatever, started to be undermindes when news outlets agreed to a "house style" that replaced the word sex with gender, maybe as much as 20 years ago.
It was only when there was the big campaign to object to the attempt to make the GRA closer to self ID etc., that I first reaslised how gradually it had happened.
As we know over the years words and usages change.
But I suspect that getting the media (which then means most of the population) to substitute gender for sex may just have been as a result of active campaigning by certain groups.
We do really have years of women's rights including accurate language being distorted that need to be returned to what it should be.
