It's like women shouting "Women have 40% lover average income!* and then when someone mentions something like men have 40% longer prison sentences there's an elephant in the room. Whereas the first case can be put down to issues like paternity, more likely to take a part time job and stuff like that
Except it can't be because there's seperate studies on women with children, married women, single women etc etc and it's pretty consistent regardless. It's black and white sexism. I'd like to point out that's because on average there's more men in prison because more men commit crimes so there's less of an average to work that out from.
