"not all biological females have a pregnancy issue. so it isn't a women's issue is it?"
Not all women have a FGM issue but FGM is still a women's issue.
Not all women are beaten up at home but DV is still a women's issue.
Not all women get killed by their relatives but honour killings are still a women's issue.
Not all women get cervical cancer but cervical cancers and their detection is still a women's issue.
No doubt you see where I'm going with this.
