Just off the top of my head, in no particular order:
Incels
Afghanistan
Excessively patriarchal religions where women are totally subservient
Using sex workers
Human trafficking
Domestic violence
Rape
Low-level sexism
Andrew Tate, etc.
Erosion of women's rights including, but not limited to, transactivists
Shitty dating behaviour such as ghosting and negging
Drag / "womanface"
Yes, I know some of the above can be perpetrated by women, but it's usually men, isn't it?
