I oppose keeping parents in the dark about the sex of their child.
It would be a setback for fetal rights.
Parents have the right to know the sex of their child. In any case, if you really want to know the sex of your child, there are kits being sold on the internet for that purpose.
The onus should be on abortionists and pregnant women to not engage in sex selection abortions.
Adrian McNair had a good post about this topic.
If certain ethnic communities are the ones responsible for gendercide, they should be targeted. Not people who have zero intention of aborting a baby of the wrong sex.
