Sadly it isn't a new thing.
Women have always been damned if they do or damned if they don't.
Fridgid or a slag, while men are studs, patted on the back and praised.
I do agree with her about the backlash. There is always backlash when women inch a tiny bit for themselves. It gets bigger the more we inch forward
Men don't want to lose their power. Especially the men who hold no power over other men.
They also don't want to have to take responsibility for their own behaviour.
she believes that feminism driven by millennials has caused a huge back lash amongst men
Maybe you should as her to reflect on this and ask why, like in so many of these situations, the blame and anger, instead of being directed at the men who hate women wanting to be treated equally, it is always turned back on women?
Why are some women so angry at other women for wanting better, instead of the men who want to keep women beneath them, less than, obedient?
