If homosexuality was narrowed down to a gene or gene sequence that science developed a way to ”switch off”, if a parent chose that option, would you believe it was a parent’s right if they knew their child had it?
Let us throw in a third option C: the gay gene can only be identified, but not modified. If the parents found out that their offspring had this particular gene, would it, or should it, be their right to terminate the pregnancy instead of bringing such a child into the world?
