Are Boys the Target of a Feminist Gendercide Campaign?

Last week social media jumped on the story of a woman who supposedly decided to have a late-term abortion specifically because she found out she was having a boy. Based on a near-anonymous comment posted on an Internet forum, the story is highly questionable at best. Nevertheless, both pro- and anti-abortion advocates pounced on the missive. The dialogue generated took on a life of its own, inspiring the following comment from feminist site Jezebel:

"The virality of this story is sort of a nice reminder about confirmation bias: when something fits our preferred narrative just a little too snugly, it's probably time for skepticism," wrote Jezebel's Anna Merlan.

How, exactly, does gendercide "fit our narrative" in the West, especially in relation to boys?
