Why would a cheaper technology lead to an increase in abortions? Don't they just kill the fetus anyway upon realization of the sex if it's undesirable?
Wouldn't it ultimately be safer for the mother, to perform a very early term abortion if that's what she wants, rather than waiting?
If a mother wants to abort at 60 days pregnant (assuming the new tech enables earlier sex identification), why shouldn't she be allowed to for any reason she deems worthy?
