It’s already been mentioned (partially) but two things are wrong with this post and one major thing is right.

Firstly you are right that there is a lot of latent sexism around. I describe myself as a feminist even though I miss a lot of it while contributing to ending it.

Secondly though you are cherry picking. There are a lot of male and female a-holes on there. Also it’s poor to pick an example of the ovarian cancer leaving because that’s not really sexism it’s just a tragic relationship with lots of poor communication. People split up over how many or when or whether to have kids all the time sadly.
