How do pro-choicers deal with sex selection abortions?

Very carefully. It's a tight line to walk as Deepali Gaur Singh shows at the RH Reality Check blog:

A complicated issue nonetheless, it needs to be seen exactly like that—without simplistic answers. While the agency of the woman in choosing to keep or terminate a pregnancy is unquestioned, how does one deal with this if it means termination of a pregnancy because of sex? And this is truly the irony of the situation: an argument meant to empower women and their bodily sovereignty can so easily be used to hijack the idea of agency for the woman while also wiping out a fifth of the female population of the country.

How do you show your abhorrence with killing female fetuses simply because they are female without undermining the idea that women should be allowed to have abortions for whatever reason they choose?
